Confetti Bomb Prank!





Introduction: Confetti Bomb Prank!

Pull this one on your co-workers or fellow computer geeks! Very simple to do, but very effective.

Watch the video for the overview:

Step 1: Supplies

The supply list for this prank is short and they are easy to find:

1. 35mm canister

They will give you these for free at Walgreens or most one hour film development labs.

The white ones with the tighter lids work better than the black ones.

2. Can of compressed air

Your common air duster - found at most offices. Used for blowing the dust out of computers and keybaords.

3. Some confetti

I bought some for a dollar to make it stand out more in the video, but those holes from the hole punch work great!

Step 2: Fill the Canister

This part is simple - just turn the can of air upside down, and then spray a little of the liquid inside.

WARNING The liquid inside is extremely cold and extremely flammable. Caution is advised, especially when dealing with something that can both cause frostbite and severe burns.

Once the liquid is inside, quickly dump as much confetti inside as you can, without getting any in the way of the lid. (If the lid cannot close tightly, the pressure will not be able to build.)

Finally, close the lid tightly, set it next to your intended victim and then quickly walk away!

Step 3: Kaboom!

Now comes the kaboom.

It will take anywhere from 5 seconds to a good minute to explode, depending on several factors.

If you spray a lot of liquid inside, it will take longer to evaporate and build up pressure.

If the ambient air temperature is high, the liquid inside will likely evaporate much faster.

For a bigger boom, turn the canister upside down and use more liquid. Stand clear of it if you do. The resulting explosion is pretty violent, especially for a little canister.

Watch the video again to see what I mean. I filmed that in my garage, where the ceiling is about 15 feet high. Listen to how fast the canister bounced off the ceiling and then the floor again.

    i dont get it. how does this work?

    the super-cool liquid is a gas, when it is sprayed in the canister it turns back to gas, causing the pressure to build untill...BOOM

    I see. So it's naturally a gas at room temperature but liquid in the can until sprayed, so if it's sprayed into the canister as a liquid it will want to change back to a gas, hence building pressure and ultimately popping off the canister lid? Am I getting this right? anyone...?

    you are totally getting the concept

    Also the cold air expanding will create preasure. :D

    lol i almost got suspended from school

    LOL I made a dry ice bomb and got extra credit lol

    NO WAY! LUCKY LITTLE SON OF A was a bomb....but it went didnt technecally it was,but it didnt me and a friend picked it up and took the cap off (really really really stupid idea now that i think of it!) we had some SUPER CARBONATED WATER that stuff will BURN your mouth ha ha ha ha ha....

    That happened to me too except it was a little embarrassing when like 5 people were watching expecting a giant boom and ending up with some really corbonated water.
