Picture of Crazy Diaper Prank
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...

Picture of 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...

Picture of 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.

flamming hands = SPA(hydrated) layer on hands + cotton soaked in alcohol + lit match.
the stuff is able to withstand a blowtorch as long as it has a good amount of water and so would do the effect nicely.

Also, if you have a super high-speed blender (such as a vitamix) you can grind these pellets to powder. It makes the "solidifying" almost instant, so you can do the dump while they're still at the table when they just look away.

Would these crystals also work to keep moisture out your toolbox?

Don't the little poly-sorb beads/crystals come in some shoeboxes too?

Kasm279 (author)ToastaG2009-12-31

 They aren't the same thing but they do the same thing. The Silica stuff you are talking about also comes in camera bags, backpacks, just about any bag really...

my mom's boyfriend had some strawberry cake, and i put ketchup on it, you could not even tell, and he was all eating it, sits for a moment, and spits it out.

junits15 (author)2009-06-28

That laughter at the begining and end of the video is serously creeping me out!

lemonie (author)2009-03-27

Can you buy this stuff in bulk? I don't want to be seen buying diapers, but this is pretty neat. L

fallenspirit123 (author)lemonie2009-06-08 has it

cyrozap (author)lemonie2009-04-28

The internet is your friend.

rulenumbaone (author)2009-06-07

I have dne simpler/similer by dropping a tampon in a friends cup of coffee while he was in the Loo. Funny

awang8 (author)2009-03-29

Cool! Does it go solid or just slimy? If it's solid is it bouncy? Cause if it in I can make a couple of bouncy balls (I have moulds).

swartley3ga (author)awang82009-05-31

look up the instructable for how to make a bouncy ball it's pretty good

Hugo4123 (author)2009-05-04

finally i have found your account on instructables

finfan7 (author)2009-03-28

I don't recommend using a worn diaper even if the baby is clean. Hilarious idea. You can actually buy this stuff pure or possibly something very much like it from places with stuff for flowers. It is used to make vasefuls of unspillable water.

bwpatton1 (author)finfan72009-03-31

You can also buy it in Hobby Lobby, its that fake snow stuff, made out of the exact same things.........??>......

yeah568 (author)bwpatton12009-04-26

My sister actually got some of the stuff from our local science center. A tiny bit (Like a teaspoon or so) expanded to cover an entire sheet of paper.

fusion (author)2009-04-14

magic stores call it slush powder prank stores call it instant snow you can get it in larger amounts from adult diapers (don't ask)

struckbyanarrow (author)2009-04-09

grizzledcamudgen (author)2009-04-08

ShadowJesus (author)2009-04-07

caycee (author)2009-03-29

rattyrain (author)2009-03-27

Berkin (author)2009-03-26

Oh, cool! I used to have loads of this stuff from my Chemlab. Sadly, I used it all to make fake snot. :(
