3The Water and Whiskey Anti-Gravity Switcheroo
Speaking of learning the magic of science via alcohol, here's the kind of trick they teach in Bartender School.
This one happens with the help of the only liquid in the known universe with more magical properties than water: whiskey. Pour a shot glass full of whiskey, and another full of water. Slap a playing card over the water, and turn it over on top of the whiskey, like so.
Pull the card aside slightly, and the water and whiskey, instead of mixing, will neatly switch places
This does require some patience though, since the whole thing can take 10 minutes or more.
It works because whiskey is 40 percent alcohol, which is less dense than water. When the water glass is inverted and the card is moved to allow a tiny gap, the water trickles through, unseen. The whiskey, being lighter, is forced out of the lower glass into the upper. Scientists compare it to the jocks kicking the nerds out of the dorm in Revenge of the Nerds.
2Make Instant Snow From Boiling Water
This one requires it to be really, really freaking cold outside. Like way colder than it probably gets where you live. But get a day way below zero, boil a cup of water, and toss it into the air. The results are as cool as shit:
If it gets to be 30 degrees Fahrenheit or so below zero, the water vapor will freeze instantly. That's why the water has to be boiling, as the vapor has a much higher surface-to-mass ratio (the same reason you will freeze to death slower than say, a mouse).
All of those little heated particles of water cool very rapidly when exposed to super cold air, forming ice crystals in an instant. BUT ONLY IF IT IS COLD ENOUGH.
We do the all caps there because once again we fear somebody going out on what's considered a cold day in California (say, 60 degrees) and tossing a pot of boiling water toward their friends. And then suing us.
