Pranks For Sleepovers

For many of us, gathering with a group of unsupervised peers and scaring the shit out of ourselves was a rite of passage. At slumber parties we watched horror movies, told ghost stories and strapped ourselves to railroad tracks while high on cough syrup.

Scariest of all were the games that everyone seemed to know, even without the benefit of YouTube tutorials -- tricks that supposedly unlocked magical powers or malicious spirits. And the funny thing is, these games have been going on for generations because on some level, they work.

For the holy grail of pants-shittingly horrifying party tricks, look no further than Bloody Mary. The game goes like this: You stand in front of a mirror, alone, in the dark, and say "BLOODY MARY BLOODY MARY BLOODY MARY!" And then (allegedly) a woman appears in the mirror. Then she scratches your face off.

But after weeks of searching through archived newspapers and microfiche, we havent actually found anyone who summoned a psychotic person via mirror. Still, at this very moment, somewhere theres a 12-year-old kid standing in a bathroom whispering "Bloody Mary" loud enough for her giggly slumber party guests to hear her. Do you know why?

If you stare at a mirror long enough, youre going to see some freaky shit.

One psychologist set up an experiment where he had 50 people gaze at a dimly lit mirror for 10 minutes. Afterward, participants wrote down what they saw, if anything. Before we share the results, bear in mind that this was not a slumber party and no one was told theyd see anything horrific beforehand.

Why? Well, for one thing, if you stare at anything long enough -- and we mean just stare at it, not look at it while doing something else, like shaving -- your vision starts to distort it. One reason is the Troxler effect. Stare at the target below for 20 seconds or so:

Did the dots start to disappear after a while? If not, you did it wrong. The idea is that our brains are wired to stop taking in the same thing over and over again, just for our own sanity. Imagine always being aware of your limbs, of sitting in a chair, of every breath and every blink. Life would suck. So, as a neat trick, our neurons cancel out information thats constant.

What does this have to do with Bloody Mary? Because our faces dont have a central point, like that target above, its the whole face that starts to blur, or distort, as our brain starts to cancel parts of it out. The result is some kind of horrific monster face, staring back from the mirror. And of course, "Bloody Mary" cant actually attack her victim as per the legend, since said victim quickly runs squealing out of the bathroom before she gets the chance.

For kids who have no problem putting their fingers on their friends butts, this game is a slumber party staple. A volunteer lays down on the floor, usually with the arms crossed over his or (who are we kidding?) her chest. Another four sit around her and attempt to lift her body using nothing but their index and middle fingers. At first, the attempt fails because the lifters arent tapping into the magic power yet -- it only proves that under normal circumstances, a person is too heavy to lift this way.

But then begins the chant: "Light as a feather, stiff as a board. Light as a feather, stiff as a board." A countdown follows: "1, 2, 3 and LIFT."

This time, up the body goes, with only finger power lifting it.

There are a number of things going on here, and none of them require the devils interference, fortunately.

It begins with that first attempt, the one that fails. You may be shocked to know that it isnt a lack of faith or witchcraft holding everybody back, but the fact that the group isnt really coordinating their lifting. Frequently, participants are told to just try hefting little Madison off the floor without any kind of initiation or plan, causing the kind of completely disjointed and bullshit effort you get from a bunch of teenage girls.

But synchronize the four lifters eight index and middle fingers together, like, oh, maybe with a chant, and suddenly you have more than enough lifting power to heft a schoolgirl. And note that limiting the lifters to two fingers isnt much of a disadvantage -- the index and the middle fingers are the strong ones (if you dont believe us, take note of how you carry your groceries next time). Louis Cyr, an old-timey strong man, could lift over 550 pounds with just his middle digit. We were going to add another joke here, but then we saw this picture ...

... and decided there was nothing else to say about Louis Cyr.

Anyway, thanks to perfectly synchronized fingers, the volunteer ascends easily and really, really high, too, right? Well no, not actually. The other thing about this game is the magic of exaggerated memories.

No one will accurately remember just how high they were able to lift Kaitlyn last night at the sleepover. Dr. Karl S.
