Did your science teacher ever make the mistake of showing off a cool science trick? And then they couldn't get the class to listen to the following lecture explaining why that thing went boom/shot liquid/turned colors/flew into the air/lit Denise's hair on fire? My science teacher did that all the time. (And then he taught us that Jesus rode dinosaurs, for which I am forever both bitter and thankful.) Watch these videos of 10 fun science tricks, and try not to learn anything.

1. Elephant Toothpaste

Instructions: Drop potassium iodide into dishsoap and hydrogen peroxide.
Effect: Foam shoots out of a bottle.

2. I Believe I Can Fly

Instructions: Carefully place a paper airplane between two opposing fans.
Effect: Hovering airplane. And possibly an art grant.

3. Shelling an Egg

Instructions: Leave an egg in a glass of vinegar.
Effect: The egg shell reacts with the vinegar and creates carbon dioxide, leaving an intact raw, shelled egg.

4. Screaming Balloons

Instructions: Put a metal nut in a balloon, then blow it up and spin it in your hand.
Effect: A really annoying whine.

Just realize that with a certain age range, you won't get the science across, but you'll be handing them noise-makers:

5. Freeze a Beer

Instructions: Stick a beer in the freezer for five hours. Tap it hard.
Effect: Instant frozen beer. For the best effect, pour a little of the beer out before you freeze it. "Look! It's liquid! But wait!"

6. Teabag Rocket

Instructions: Empty a teabag and stand the hollow tube on a table. Light it on fire.
Effect: Burn the house down.

7. Dry Ice Condom

Instructions: Drop dry ice into a condom full of water.
Effect: Exploding condom! (Common problem, amirite guys?)

8. Mentos and Coke Rockets

Instructions: You've seen the Mentos and Diet Coke guys. Do that. But this time, close the bottle right after you drop in the Mentos. Then slam the bottle on the ground.
Effect: The bottle flies into the air. On, like, the fifth try.

9. Invisible Extinguisher

Instructions: Mix a little vinegar and baking soda at the bottom of a pitcher. Pour over open flame.
Effect: The flames go out, but you can't see what's doing it. (Spoiler: It's the carbon dioxide from the vinegar reacting with the baking soda; it's heavier than air so it sits in the pitcher and pours out when you tip it.)

10. Ruben's Tube

Instructions: Perforate a tube, seal it, run gas through it, and light the escaping gas on fire. Now run sound through the tube.
Effect: A flame-based equalizer.
