Laughing Coke Can Prank

Laughing Coke Can Prank
This instructable details how to make a coke can prank (or any drinks can) that will laugh when picked up and tilted towards the mouth.

It's a great prank to play on friends/colleagues/family when you get a chance to swap out their drink for your rigged one!

I tried to make this ible as simple as possible to make it accessible to as many people as possible. Where I could I taped instead of soldered. Info in the steps should be transferable to most other noise making toys!

Required:

- drinks can
- toy that laughs
- tilt switch
- batteries
- electrical tape
- solder

Tools:

- wire strippers
- soldering iron
- hammer
- punch or nail
- hacksaw blade or scissors
- pliers

Turn over the can. For items required in this step, see picture two.

With a punch or nail, pierce the bottom of the coke can. Wiggle it until the hole is wide enough to insert a hacksaw blade.

Gripping the hacksaw blade in the pliers (or your fingers if you're hardcore), cut a slit. Cut two more slits so the bottom of the can is divided into six. Once the hole is larger, using a strong pair of scissors may be easier than the hacksaw blade.

Carefully push the six tabs inwards to make a hole. Dividing the bottom of the can more is better, it will cause the rim to bend less and your can won't wobble then.

You should put something that vibrates on it instead of something to make sound.  That way, it spills all over them!

I showed my cousin this and he did it on me when I was unsuspecting, switched my coke can for his when I took a piss. I nearly had a heart attack!



P.S. Why do you "take a piss" when you are giving the toilet your piss?

instead of worrying about precariously soldering a wire to each of the ends, why not put the tilt switch on one of the battery leads? you could just bridge the push button sensor withsolder or something. Just an idea.

Glad I could help.
Mar 11, 2010. 6:00 AMbeehard44 says:

Jan 2, 2010. 5:10 AMgodofal says:

the can is still in the fridge...
we dont have soda that much, so if we have it we already kinda know its for somebody, so we dont take it :P
maybe i should give it to someone, then il have the chance to video it to :P
Jan 24, 2010. 1:47 AMgodofal says:

I am clueless about how to make most of the projects on Instructables. I guess I just live vicariously through you guys. I am more than happy to give you 10/10 but I don't see were it is on the page that I can vote.
Jul 30, 2009. 8:17 AMporcupinemamma says:
Voted! :0) I don't know how to work with LED's I have thought of one particular project I would love to do, and I got supplies from radio shack, but was frustrated because I couldn't apply them to my project.
