Perfect for April Fool's Day! It's not what you think. Play this easy and funny prank on your friends.

Watch the video for a bonus prank.

Step 1: What You Need...

1. A Diaper
2. Scissors or razor blade
3. A Glass of water
4. An Unsuspecting friend or enemy.
OPTIONAL: A cool Zildjian T-Shirt.

Step 2: Get It Ready...

Using the scissors or razor blade, cut through the liner of the diaper. Inside you will find the precious "pee-pee crystals" which is actually called Sodium Polyacrylate. Remove the cotton inside by tearing pieces of it out and placing them in a covered container. Also dump in any of the crystals you may find in the bottom of the diaper. Now shake the container real good for a while. Remove the cotton and you should end up with about a handful of crystals.

Step 3: Do the Prank...

Store the crystals in a zip lock or other small container. When you are at the restaurant or even at home, wait for your friend to leave the table or distract him long enough to dump the crystals into his glass of water. In about 20 seconds, the "pee-pee crystals" will absorb all of the water in a full glass and turn it into a solid mushy glob of rubber. Play stupid and surprised at what could possibly have happenned to the water.

BONUS: Call the waitress or manager over and ask "WTH!!???"

WARNING: Do not eat or let your friend drink from the glass. Not sure what could happen but it certainly will not be pleasant.

I hope you enjoyed this April Fool's Prank you can use all year long.
