New Zealand agriculture aims to invent a lucrative market for red deer milk

In the 19th century, Europeans imported red deer to New Zealand so that they could be hunted for sport. Apparently that hasn’t help people’s interest sufficiently, and New Zealanders like Steve Carden have been looking at new ways to fit these deer into people’s lives. Without much demand for venison, Carden and the state agricultural company Pāmu, are now marketing deer milk as a new dairy option for human consumption. With supposedly intense demand from top chefs, the milk likely won’t be putting cows out of a job any time soon, instead joining the ranks of interesting but still unusual forms of dairy that people harvest from our fellow mammals.

Difficulties of milking deer

Every mammal seems to have its own recipe for milk, and the red deer (Cervus elaphus) are no exception. While cow’s milk is noted for its bland sweetness with enough fat to separate out into cream or cheese, deer milk much closer to cream from the start. The low sugar, high fat, high protein milk probably wouldn’t be too attractive as a beverage, but it it proving to be very attractive to chefs. The expectation is that the milk will be raised as an expensive, niche product to excite foodies even if it comes with a premium price.

That marketing angle isn’t just because of the way the milk tastes. Thousands of years of domestication, plus the naturally robust output of larger animals like cows, means that dairy cows can produce over 100 pounds of milk a day. The deer, on the other hand, aren’t about to line up to be milked, and when they do cooperate, only offer around a half-pound of milk a day. So even if people with well-trained palates really appreciate this new source of calcium, economics will keep most of us from ever tasting it.

Milking many types of mammals

Red deer may lie on the fringe of non-cow dairy production for humans, but this isn’t the first attempt at getting milk from deer. Reindeer used to be milked in Scandinavia, and moose are still milked in parts of Russia today. Sheep, goats, camels, buffalo and horses are all milked in various parts of the world, although the qualities of each species dairy sometimes limits how the milk gets used- if the sugar or fat content is wrong, the milk might not be usable in things like cream or cheese. To come full circle, Pāmu does have another niche to target if their red deer milk doesn’t get used in cooking all that often— the high protein content apparently also makes it a candidate for use in cosmetic products, which sounds oh so delicious.

Iceland’s Christmas book flood encourages everyone to indulge in an evening of reading

Twas the night before Christmas, and all across Iceland, every person was up reading, new books in their hands. The books had been picked with excitement and care, for the night of jólabókaflóð finally was there…

It’s fair to guess that this couplet doesn’t describe most people’s Christmas Eve, because with a population of only 319,000 people, most of us don’t live in Iceland. For residents of this small island nation, the tradition of jólabókaflóð (“yo-la-bok-a-flot”), or “Christmas Book Flood,” means that December 24th is a time to  give books as gifts, then spend the rest of the evening reading. Unsurprisingly, Iceland boasts some of the highest literacy rates in the world, much of which is likely attributable to this annual exchange of reading material.

Rationing and reading

Even though most publishers don’t release books until November of each year, Iceland takes reading very seriously. 93 percent of Icelanders read at least one book every year, but 50 percent read at least eight. So even if less than a 1000 new Icelandic titles are published each year, they’re being read by a bigger portion of the population than in other countries. This probably helps encourage people to write more too, as on average, ten percent of the population will publish a book at least once in their lifetime.

Iceland’s love of literacy wasn’t completely organic though. Jólabókaflóð, in particular, can be traced back to events in World War II, when many materials were being heavily rationed after Iceland gained independence from Denmark. Paper, however, was relatively easy to obtain, making books the easiest and widespread gift option for the winter holidays. This was codified, also in 1944, by the Bókatíðindi, or “Book Bulletin.” Like a much more civilized version of Black Friday shopping, the Bókatíðindi is sent out to every citizen by the Icelandic publishing industry each November, kicking off holiday shopping for the whole country.

Reaching more readers

In a time when reading material is everywhere, jólabókaflóð is still going strong. Electronic books have seen slow growth in Iceland, largely because of the desire to gift substantial books as gifts. Most titles are still published in the winter only, although some, like translations of Harry Potter, have warranted publication dates in the spring or summer. And while speaking Icelandic helps with pronouncing a word like jólabókaflóð, people from other countries have been doing their best to adopt some form of Christmas book floods at home, adding new stories to their Christmas Eve traditions.

My four-year-old asked: That’s weird. Do kids still get toys too? It’s weird.

Yes, but probably nothing gigantic. Instead of a heap of presents under a Christmas tree, kids put their shoes in the window at night, and one of thirteen Santa’s will leave them some small gifts or fruit in the morning. Bad kids don’t get coal, but may end up with an uncooked potato.

Gravitational waves help scientists spot the collision of two neutron stars

My daughter loves hearing about astronomy, as the movement of the planets, the unfathomable scale of the universe, and unanswerable questions like “is the universe contained in something?” really excite her imagination. So with today’s announcement that astronomers had finally observed the collision of two neutron stars, it seemed like the perfect story to share with her. If only we hadn’t gone out for candy-laden frozen yogurt an hour earlier…

Me: So once up on a time, two stars blew up.

Four-year-old: That’s bad.

Eight-year-old: It happens eventually to all stars, right?

Me: Well… many of them? The point is the stars were the right size to use up all their full, supernova and be left as neutron stars.

Eight-year-old: What’s a neutral star?

Me: “Neutron,” but that’s a good connection to make. A neutron star is the remains of a star that’s basically made of neutrons, which is a neutrally-charged part of an atom, as compared to positive protons and negative electrons. Anyway, the important thing here is that a neutron star is incredibly dense. You remember density?

Eight-year-old: That means it’s… hot?

Me: No, it’s not about how much energy it has, but how tightly packed together all of it’s material is. So in this case, imagine something that if you put it on Earth somehow would weigh more than our Sun, but was small enough to fit in a space between San Francisco and the San Francisco Airport.

Kids together: Whooooaa…

Me: Yeah, it’s so packed together that–

Eight-year-old: But is it hot?

Me: Well, it’s not inert. It has some some energy as we’ll see, but I’m not sure about its temperature. [Post-bedtime fact-check: Neutron stars are hotter than Earth, but cooler than most stars.]

So the mass of a neutron star is so dense that a teaspoon full of neutron star would weigh a billion tons. They’re a ton of stuff in a small amount of space. But all that ‘stuff’ means that they have a lot of gravity, which is imporant when these two stars started circling each other. As they drew closer, they started orbiting each other, but also tearing each other apart.

Kids: Oooo….

Me: As they spun closer and closer, their immense collective mass started emitting gravitational waves. Do you remember the last time we heard about those?

Eight-year-old, now hanging upside-down off the couch: Uh….

Me: We last heard about this when new sensors detected two black holes crashing into each other. The impact send out waves that were basically warping the universe just a tiny bit, and sensors at two seperate buildings were set to notice when lasers were stretched a tiny bit?

Eight-year-old: Oh right!

Me: Well, those two facilities were called LIGO [Laser Interferometer Gravitational-Wave Observatory], and now a third set of sensors has been set up in Italy, called VIRGO, which is doing the same job. To get back to our neutron stars, we know that 130 million years ago, the two stars finally collided, because the waves from their collision arrived at the Earth, and were picked up by these sensors, around two months ago.

Eight-year-old: Two months ago?!

Me: The collision was very far away- around 130 million light-years. The cool thing was that when the gravitational waves were detected, people were notified to jump into action and start looking for the light that they were expecting to follow.

This kind of collision had been predicted, and the size and shape of the gravitational waves looked like what people expected of crashing neutron stars. So they thought that, unlike a black hole, there’d be some light for telescopes to see. Lots of people at observatories around the world started scanning the sky to find traces of the exploding neutron stars, which is called a kilonova.

Four-year-old: What’s an observatory?

Me: A place with a high-powered telescope.

Eight-year-old: Does that mean it was in the sky the before? Did the constellation [Hydra] change?

Me: They did get to see it, but it wasn’t previously visible.

Many, many teams started working together to look for the colliding neutron stars. One guess is that 25 to 30 percent of all astronomers on Earth helped out with this to get as much information from different telescopes as possible. Finally, someone [Charlie Kilpatrick] from UC Santa Cruz, nearby, found a new bright spot near another star. He told everyone to “look over here!” and you could see a blip appear over time. First it was blue, then red, and then dimmed away to nothing.

It was emitting light, but also something called gamma radiation, which is just a form of energy. We can’t see it, and it usually just flys right through us without doing anything. A lot of it was released in the collision, which is what all the telescopes were really looking for.

We had talked about what it meant to be an “author” on a paper the other day, right? Well, one of the papers about this event has about 3,500 authors on it because so many people helped out.

Eight-year-old: You’re like an author, right Daddy?

Me: Well, not like that kind of author.

Eight-year-old: But you write about science stuff.

Me: But I’m not contributing to experiments or anthing. It’s different…anyway…

Eight-year-old mumbling something…

Me: Because there was so much mass and energy between the two stars, when they smashed together they could essentially make a lot of new atoms. Not making them out of nothing, but recombine material to make new atoms that don’t get created all that often. Most new atoms made by stars are light, like hydrogen, but in this case the neutron star was making heavy metals, meaning silver, gold, platinum, and…

Eight-year-old: Gold?! Oh! Money money money money money…

Me: Uh, yeah. They estimate that there was probably so much gold created in this collision you could ball it up into something the 10 times the size of Earth.

Both kids: Whoaaa….

Eight-year-old: You could be soooo rich!

Me: If you could do something with it, yeah. We use gold for lots of stuff, like some of Mommy’s jewelry, or inside electronics like cell phones, and–

Four-year-old: I want to see Mommy’s jewelry!

Eight-year-old, upside-down again: Inside phones?! Money money money money money…

Me: Ugh… right. So to have any of these metals on Earth means that before the Earth was formed, other neutron stars must have collided and released all these metals, some of which got bundled with the other rocks and dust that eventually clumped together to form the planet. We now dig these things out of the ground to use for all sorts of stuff, like earrings or even dipping strawberries

Eight-year-old: People do that? What?!

Me: Yeah, we put use gold for all kinds of things, but my point is that none of it was from Earth originally. It all came from these huge explosions in space!

Eight-year-old: …my friend said she bought gold for two dollars. Is that real?

Me, realizing I’ve totally lost my audience: If it was a small amount. Two-dollars worth of gold.

Eight-year-old: So it’s made up? The price?

Me: Prices are only what we decide… look, people predicted this is where these heavy metals came from, and now for the first time we’ve been able to observe that happening. We’ve never seen neutron stars colliding before! This work also helps us learn about the expansion rate of the universe, because we can now compare the speed of the gravitational waves to the speed of the gamma radiation. It’s also an amazing project to have so many people working as a team across the globe in a way that just wasn’t possible before!

Eight-year-old: …

Me: You know, platinum is worth more than gold per ounce?

Eight-year-old: Money money money money money…

Me: Bed time?

The scientific underpinnings everyone’s favorite fidget spinners

As the parent of a second grader, I’m apparently obligated to have an opinion or concern over the fad/scourge/salvation known as fidget spinners. Our household now owns a lovely metallic-purple spinner, and it hasn’t made a huge difference in our lives one way or the other. This may be because they’re just toys exploiting kids’ (humans’?) desire to keep up with their peers, but it may also be because fidgeting isn’t often an issue my daughter seems to struggle with. This point may actually tell me more about my daughter than the spinners though, as some researchers suggest that the toys are sort of a tool for self-regulation, and as such every person may benefit differently from playing with them.

The fuss about fidgeting

For those of you outside the parenting bubble, a fidget spinner is a flat, three pronged piece of metal or plastic with rounded edges. Each prong flares out wide enough to accommodate a small disc inside that can turn on internal bearings. In the center of all this is another disc, which again can turn on internal bearings. You then interact with a spinner by holding the center disc like an axle, flicking the outer prongs to watch it spin. It’s oddly satisfying just to flick, but some kids take it farther by trying to do tricks, and in some cases, accidentally discovering rotational inertia (more on that here).

The fidget concept is that instead of getting distracted during an otherwise sedentary activity, like a classroom lecture, you can keep your hands busy with your spinner. This isn’t actually that odd an idea, and many adults that twiddle pencils, click retractable pens, or maybe doodle already employ the same strategy that spinners promise— by giving your hands something to do, you’re actually fine-tuning your stimulation levels. If all goes well, you should be able to improve your overall concentration by finding just the right balance of activity levels. For some people, an object to manipulate in their hand might not be necessary. For others, those small amounts of movement may really make a difference— some studies have found that kids who have something to wiggle with actually have their test score improve.

Finding the right balance

The downside of fidget spinners may be that they can occupy too much of one’s attention. If you go beyond just flicking them in your hand by attempting balancing tricks, you’re likely to want to look at the spinner at the same time, which will draw you away from class, your meeting, the deposition, etc. In that sense, clicking pens or other toys, like fidget cubes, may be superior at helping us moderate our activity without demanding too much concentration. In some cases, the best option isn’t in one’s hands, but under one’s butt— our local elementary school will let kids swap their chairs for exercise balls, which is basically another way to let students manage their activity and stimulation.

So a fidget spinner may not be a bad idea, but it may miss its design goals ever so slightly. This imperfect match for their stated purpose of managing activity and stimulation may doom them to being the fad many are labeling them as, but that doesn’t mean the underlying ideas aren’t worth paying attention to.

My second grader said: I can balance my spinner without looking at it! Look!

Mop-up teams fight the fires that might flare up behind the fire line

Battling wildfires is an enormously involved process, and it continues on long after the walls of flame have been extinguished. The first goal of dealing with large wildfires is to contain them, creating a perimeter where there is no more fuel, or fire, to burn, keeping things from spreading further. Once that perimeter has been established, it needs to be maintained, which is where the mop-up teams go to work.

Mop-up teams are in charge of making sure fires don’t get restarted behind the fire line. Forest fires can burn hot enough to leave smoldering embers and ash buried under dirt and rocks, even without the presence of visible flames. Since a shift in the wind or hotter day can push these hidden heat sources back into the danger zone, mop-up teams have to carefully sift and dig through burned areas to make sure everything is really extinguished.

Low-tech tools

Rather than fire trucks, mop-up teams rely on a less mechanized tool set for their work. Pulaski, which are a sort of ax-pickax hybrid, is used to chop and break up soil and clumps of foliage. To see how hot soil may be at any particular location, these firefighters simply pull off a glove to feel the temperature with the back of their hand. If a hot spot is found, it might be “dry mopped” by mixing in cooler soil, or “wet mopped” by spraying additional water to cool things off.

Potential perils

While these teams shouldn’t be facing walls of flame when mopping up a burn site, they’re certainly not out for a picnic either. Firefighters may still deal with long, physically exhausting shifts as they dig and hack their way through smoking forests. Burned trees are often structurally unsound, and prone to collapse, possibly revealing fires hidden in their branches or trunks. Ash pits are another common hazard, as trees and roots that have burned away may leave hidden cavities underground. As a firefighter walks through the area, they may suddenly find themselves waist deep in hot ash, as the ground beneath their feet collapses.

Even after the mop-up work is done, the fire management still isn’t complete. To help get burned areas back to normal as quickly as possible, teams of soil specialists move in to assess the damage, and prescribe next steps to rehabilitate the lost flora. Some of this is to restore the woods quickly, but a more immediate concern is to fend off erosion and possible mudslides, as the burned plants and their stabilizing root structures will be sorely missed at the next windy or rainy day.

Crafting furniture through careful cultivation

My wife just completed building an eight-foot table for our porch. After watching the sawing, drilling, sanding and staining, my first grader suggested that “next time” she try getting a really big log, and just carving a table out of one piece of wood. The conversation then drifted into hypotheticals about the size of the tree you’d need for a table this size, but the basic notion that furniture doesn’t have to be assembled isn’t actually far fetched. Some items can be carved, and others can just be grown and harvested.

If you look for “single log” furniture, it will often refer to pieces that have been sourced from a single tree, often with some traditional assembly involved. The advantage of this concept is that careful planning can help reduce the amount of wood wasted if nearly every piece goes back into the furniture in question. If you’re willing to deal with more waste, you can skip all the screws and nails by carving a whole log, most often with a chainsaw.

A seat from a sapling

For minimal material waste, both from wood or fasteners, you should probably just grow your furniture. People have been guiding and shaping trees and vines for ages, which can produce results comparable to an all natural 3D printer. To achieve more complex shapes than a round stump, branches of willow, oak or ash trees can be grafted together, forming a natural weld, so to speak. With planning and patience, this can allow for a variety of forms, even incorporating some elegant decoration beyond the object’s structure. More complex items need more time to grow, but an elaborate chair can be harvested after 11 years, with only some pruning and finishing to be complete.

For the most part, this kind of “manufacturing” is too slow and labor intensive for mass production. A firm called Full Grown Ltd. is trying to prove that growing complete furniture is viable though, especially in light of the energy savings involved. They estimate that growing a chair at once may offer as much as 75 percent energy savings over traditional harvesting, planing, preparation, etc. (although shipping a full chair is trickier than something that can be stacked and shipped flat.) Full Grown Ltd. is looking to make the process as streamlined as possible though, with a willow chair requiring as little as four years to grow. Other products include spiraling lampshades as well as tables, although achieving a single smooth surface is obviously a challenge.

No need to harvest

If a grown chair still seems too invasive, tree shaping can make you a seat that doesn’t need to be cut down. Similar to grown furniture, guides and grafting can achieve complex forms in tree trunks, to the point of becoming living sculptures. The one catch is that your living tree-chair is probably even harder to relocate that the hulking log my first grader proposed we carve on our porch.

Railroad delays shuttering station for one last student commuter

If a train goes to a station where there’s nobody to ride it, does it make a stop? Considering the expense of operating a train as a commuter vehicle only makes sense if you can sell tickets for the majority of seats, it would probably make sense to skip that station, and maybe even close it altogether. A number of small stations throughout rural Japan are slated to be closed due to lack of ridership in the coming year, but in the Hokkaido area, cost efficiency is taking a back seat for the benefit of a single rider. The Kyu-Shirataki Station is apparently being kept open for the convenience of its last regular passenger— a high school student who uses the train to get to school.

Reduced ridership

The Kyu-Shirataki Station is on the JR Hokkaido Main line, located 807 miles north of Tokyo. Thanks to dwindling rural populations and the end of freight services on the line, the small station has been seeing less and less use. This pattern has being playing out all over Japan, shifting demand from remote stations to more densely populated urban centers.

As service winds down at the 70-year-old station, the schedule has been tailored a bit to the needs of the student who uses the station. The two scheduled stops per day are meant to accommodate her school schedule, even if there are other stations available two to six miles away. Her expected graduation date conveniently coincides with the end of the railroad’s fiscal year, at which point the station will be permanently closed.

One student, but many pilgrims

While this student’s commute has attracted some attention to the shrinking rail service, she’s not the only citizen enjoying the country’s smaller train stations. Enthusiasts have dubbed these out of the way stations hikyo eki, or “secluded stations.” While seeing less and less use for daily commutes, the stations are being visited as destinations unto themselves. Suggested stops give visitors a tour of Japan’s cultural history, and begs some reflection on the current transition the country is experiencing.

Ambergris: The prized squid parts whales don’t want

You might not believe it, but the results of indigestion were once worth a ton of money. Well, not your indigestion, nobody wants that, because you’re not eating enough squid beaks to make a material called ambergris. Sperm whales, on the other hand, make this amazing material in their guts which humans have prized as an aphrodisiac, plague replant and even perfume fixative. It once sold for thousands of dollars an ounce, none of which helps the whales very much.

Digested and rejected

Ambergris has been found washed ashore in a variety of shapes and sizes, from 15 grams to 110 pounds. By the time it’s washed ashore, it’s usually hard with a crusty or waxy color, and is even capable of fossilization. It’s not a mineral though, as fresher samples are fatty, soft and stinky, hinting at its origin in the irritated gut of a sperm whale (Physeter macrocephalus). When the whales are gobbling squid, their hard beaks don’t always go down as easily as their soft bodies, and so the whale will generally try to cough or vomit the beaks back up. If it’s too far down it’s digestive tract, the beak gets coated in a greasy substance to ease it’s eventual ejection along with the whale’s poop.

Salable smell

While this all sounds rather unsavory, the hardened clumps of ambergris have a much more pleasant smell than you’d assume. It’s been burned as an incense since Ancient Egypt, even being added as a scent in cigarettes. During the Black Plague in 14th-century Europe, people would carry a pellet of ambergris on a necklace, hoping the smell would ward off any foul air they thought carried the plague (no word on if the smell repels plague-infected fleas.)

More recently, ambergris was in demand as a perfume additive, driving it’s value up immensely. Perfume makers used it as a fixative in their recipes, helping the perfume stay on the body longer while at the same time lending some of its earthy odor to the mix. Demand has diminished in recent years, as chemists have been able to replicate the preservative qualities of ambergris with ambroxan. This is on top of a ban for its sale in the United States since the 1973 Endangered Species Act, preventing sales of a product derived from endangered species like our gastrically distressed sperm whales.

Managing the cycle stockpiles of Amsterdam

Amsterdam has a problem that many other cities wish they had to worry about. While many cities, especially in the United States, are struggling with clogged freeways and cramped parking options, Amsterdam is drowning in bicycles. Actually, in many cases it’s the bicycles that are drowning, as they’re literally spilling into the canals as people look for easy places to park them.

Cycling is a big part of Dutch culture, but that’s only part of why residents of Amsterdam collectively bike 1.2 million miles a day. A compact city plan in across largely flat terrain make biking a very easy and practical form of transportation. There are health benefits, plus a lack of pollution makes cycling an environmentally friendly way to get around the city. Unless you consider the bikes themselves pollution when they end up in the water.

Boating for bikes

The canals of Amsterdam have a history of pollutants, as they used to double as an unofficial public sewer. In 1860 most of these biohazards were cleaned up, and by comparison the bikes dumped in the water are much easier to handled. This is thanks to the “bike fishermen,” who patrol the canals with a boat outfitted with a giant, mechanical claw. Looking something like a scaled-up skill game from a carnival, these patrols retrieve shopping carts, scooters, and around 15 thousand bicycles per year. Some of these drowned bikes may be accidents, as there are few fences to keep them out of the canals, but many may be purposely abandoned.

Snapping up cycles

A second task force patrols Amsterdam for bikes that are illegally parked, blocking right of ways or, after two weeks, considered abandoned. Even with four-story parking garages entirely for bikes, commuters are known to cut corners either to make a train on time or avoid the hassle of properly finding a parking space. Improperly parked bikes are cut off their locks, carefully documented, and trucked out of town to a large holding lot. There they can be reclaimed, largely thanks to the careful organization of the operation. Eventually, unclaimed bikes are either recycled, resold, or even donated to other countries. People who do claim their bike get to enjoy the “ride of shame,” riding on a mostly empty road back to town while contemplating how they ended up there in the first place.

Why neglect their wheels?

So why are so many bikes tossed about in a city that loves and enjoys them? There may be just too many bikes, and they aren’t perceived as being valuable. When it’s cheaper to get a new, used bike than pay for repairs, people may just toss them in the drink. They’re even compared to disposable cups. It’s still good to have people biking, of course, but programs are being developed to reduce the need for everyone to own and maintain their own vehicle.

Amsterdam actually started a bike sharing program in the 1960’s, but it eventually failed. Other cities have since copied that idea, and now Amsterdam may be ready for a second shot at it, so that hopefully the four-story garage will be a place where bikes frequently “checked out” and used, rather than piled up to the point of frustration. Either way, Los Angeles is jealous.

Dogs have learned to look for the looks we make for toddlers

Humans likely started domesticating dogs 13- to 15-thousand years ago. While these early companions may have initially interacted with us as scavengers or hunting partners, much of our relationship and psychology with modern dogs seems to be modeled more on our children. When you gaze into the eyes of the significant canine in your life, both of your brains react with the same neurotransmitters in play when people bond with their babies. Now another parental pattern has been proven, wherein dogs look to their owners for guidance on how to handle unclear situations.

In humans, this pattern actually extends beyond parents and children, but it’s more obvious when a toddler finds themselves in an unusual situation. If they’re not familiar with something like a potentially surmountable obstacle, they’ll often look to their mom or dad for cues about how they should treat this novel encounter. If the parent looks worried, the child will usually pull back or hold still. If the parent smiles, the child will proceed to interact with whatever the item or scenario was, having understood that smile as an “all clear!” signal.

From kids to canines

While the above isn’t shocking, it is interesting how directly it seems to have been translated to dogs. Dogs were put in a room with their owners and a table fan, decorated with green ribbons to act as streamers. The fan didn’t need to an actual threat, but it was enough to make the dogs consider it for a moment.

Almost every dog followed the pattern set out by toddlers. They looked to their owners immediately, and then followed the cues set out for them. Negative facial expressions, turned backs or harsh words would all tell the dog that the fan was trouble, and to keep its distance. More positive or accepting body language would then do the opposite, and the dogs would approach or touch the streamers.

The effect was strong enough that researchers kept dogs that had had negative cues after the study was done to try to undo the original instructions. Extra treats and enthusiastic behavior was displayed to make sure no dogs went home with an overly pessimistic idea about fans they might see later on.
