How Do Fire Eaters Eat Fire?

Very carefully. No, I'm not being a smart aleck; fire eaters, from fakirs to sideshow performers, have very few secrets about their craft. Urban legend has it that fire eaters use "cold flames" that aren't hot enough to burn the skin or coat their mouths with fireproofing chemicals, but any flame from any source is hot enough to burn the mouth (how many times have you burned the roof of your mouth on something as innocent as piece of pizza?) and applying flame-retarding chemicals to the mouth can pose health risks. The tricks of the trade are precision, practice and the knowledge of one simple law—heat travels upward.

[A quick disclaimer: I am not a fire eater, and this is not a fire-eating lesson. I am a writer, and this is an explanation of how professional fire eaters do what they do. You should not use this article to practice fire-eating at home, and if you do, you cannot blame me or mentalfloss.com when your spouse/significant other/roommate/landlord/legal guardian asks you how you burned the place down. Now then"¦]

Eat Up

Fire eaters don't literally eat fire. They place flames in their mouth and extinguish them. It's like snuffing out a candle with your hand, but more impressive. During their performance, the fire eater has to remember two things: one, fire and hot air move upward, and two, don't inhale.

A fire-eater starts by taking a wide stance to keep her* balance and tilting her head back while holding the torch above.

As she lowers the torch towards her mouth, the fire eater takes a deep breath and begins to exhale slow and steady. This slow exhalation keeps the heat away from the fire eater's face as she moves the torch closer to her face and places it in her mouth. With her tongue stuck out wide and flat, the fire eater places the wick of the torch (which should be cool to the touch—fire eaters often use Kevlar thread for their wicks) onto it and partially closes her lips around the torch in an "O" shape.

So far, so good. Now the fire eater has to extinguish the flame, and quick. There are two ways to do this. The fire eater can completely close her lips all the way around the torch, cutting off oxygen and killing the flame, or she can put the flame out with a quick exhaling breath. The second method is preferable for performances where the torch has been lit for a while and may be too hot to touch with the lips.

That's fire eating in a nutshell (though fire eaters have a number of other tricks in their repertoires, like vapor tricks, multiple torch eats and fancy extinguishes). It seems pretty basic, but to do it right and make it look good for a crowd, fire eaters learn the method and then spend years practicing. If this sounds like the kind of thing you want to make a career or a hobby out of, the Coney Island Sideshow School offers classes in the art of fire eating.

* I'm going with the feminine pronoun because 1. most of the fire eaters I've seen in my day have been women and 2. I don't feel like writing he/she every time.

What Do Pets See When They Watch Television?

In 2012, a television commercial aired in the UK for Bakers dog food that was conceived and produced specifically to attract the attention of dogs. The spot used high-frequency sounds that are inaudible to human ears. In theory, the dog would be so captivated by the advertisement that owners would take note and perhaps purchase Bakers for their next meal.

This didn’t quite work. Many dogs failed to react at all, proving that when it comes to television ads, humans may be more impressionable than canines.

While pets may not be so easily manipulated, they still find the television screen interesting, sometimes reacting to other dogs, animals, sounds, or images. But what is a dog really seeing when they tune in?

When it comes to color, television is no different from reality for a dog. They have dichromatic vision, which means they see the world through the range of two primary colors, yellow and blue. (Humans have trichromatic vision, able to see the full color spectrum.) Cone cells in canine eyes are also believed to blur their sight to a degree. More importantly, dogs process the frame rate, or “flicker fusion frequency,” of screens differently than people. Humans can detect movement at between 16 and 20 frames per second. Dogs need 70 frames per second or more. If they’re looking at an older television, it might resemble a flip book or even a strobe light effect to them. (Modern sets have a faster frame rate, which is why dogs might be more interested in your high-definition television.)

That helps explain the visuals. What about the content? Typically, dogs will react to the same things that would draw their attention in a room—barking, squeaking toys, or commands. In a study published in Animal Cognition in 2013, nine dogs were observed to see if they could pick out the face of another dog—regardless of breed—on a computer screen instead of another animal or a person. The dogs were rewarded with treats with a successful choice. Though the sample size was small, it indicated dogs can recognize other dogs on a screen. (Which you likely already knew if you’ve ever observed your dog suddenly on alert when a canine appears on camera.)

If your dog used to get excited by another dog on television but has since lost interest, it’s possible they simply became desensitized to their appearance, realizing the image in front of them isn’t going to move out of the boundaries of the monitor.

Content unrelated to dogs might not be of much interest. In a 2017 study published in the International Journal of Human-Computer Studies, dogs presented with three different viewing screens didn’t exhibit any particular preference for one over the other. If they were shown three screens at one time, they seemed uninterested in watching anything at all.

The study also noted that dogs had a limited television attention span. Rather than mimic the binge-watching habits of humans, dogs prefer to glance at a screen for a few seconds at a time. But that behavior could also be breed-specific. Dogs bred for hunting might be interested in moving objects, while dogs that rely more on smell might be indifferent.

And what about cats? In a study published in Applied Animal Behaviour Science in 2008, 125 shelter cats were given a television to view for up to three hours a day. The cats were split into five groups and given a variety of programming to watch, from humans to footage of prey to a blank screen. On average, cats spent just 6.1 percent of the observation time watching the screen. When they did, it was mostly to focus on the prey.

Because cats may react to images of birds and rodents on television, owners should avoid letting them watch unattended. You can also secure the set to a wall to make sure they don’t knock it down.

For the most part, dogs and cats are far more interested in what’s going on in the real world compared to what's on TV. We could probably take a lesson from their limited screen time.
