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

Step 1: Opening up the can

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.

Adds a completely new meaning to "canned laughter"

[beehard44]

try  Pedobear-style Laughter.... or pedo seal, or pedo cat, or pedodog or pedofish.... pedo-tato, anyone?

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

[am111]

you know i did that except i rigged it to say hehehheheheheheheheh and it was a bash

[Capt. Kidd]

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?

[robinmitra1]

you have exactly same computer table as me lol

[Jayefuu]

It didn't look so heavy before I decided to carry it back from B&Q! I was :(

[beehard44]

i see you're from UK.....
first maplin, then b&q

[robinmitra1]

oo i got it from ikea tho..ya its heavy!

[tanmanknex]

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.

[Jayefuu]

That's a good idea :) In my case, the soldering was pretty easy, with other toys it might not be so your solution would make it a load easier. I'll add it in soon. Thanks!

[tanmanknex]

Glad I could help.

[beehard44]

it would also save up on the battery...

[godofal]

yay, tilt switch came in, ive soldered it, and hot glued it to a 7up can :D
its now waiting in the fridge for a helpless victim XD

gotta make a video of it in action soon, free patch for me :D

[Jayefuu]

Definitely! And will include it in the last step with your permission if you get one :)

[godofal]

sure!
well, maybe not if the victim doesnt want to >.<
and maybe u wont understand a bit of what would be said, since were all dutch...

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

[Jayefuu]

Did you get anyone? :D

[godofal]

kinda, my sister liked it and tried it on her friend, but she was to suspicious, and all they kinda did was gigle (someone shoot them for that)
its mostly becouse its to light, so im gonna add something as a weight, and see if it works then...

[Rubber Duck]

Oh boy, I think our goodwill has a tickle me elmo, but I know it has a chicken dance elmo!!!

[pyroal]

what spicific laughing toy did you use and were did you get it and the tilt switch

[confused-confucious]

THOU AVE NOT TOLD THE NERDS: WHICH TOY DID YE MANGLE FOR USING THE " LAUGHING CIRCUITRY ". NOT EVERY ONE IS CLEVER ENOUGH TO MAKE ONE OR LUCKY TO LAY THEIR HAND ON SUCH A TOY.

[mo5]

alot of fast food stops have them

[Jayefuu]

CAN HAS MORE CAPS LOCKS PLZZ?? You can get these toys all over. Tickle me elmo is a good one if you can find it cheap, lots of the talking/laughing birthday cards would be good, gadget stores usually have cheap laughing beanbags or other such laughing toys, as do most toy shops.

[pyroal]

thx didn't realize how many things make noise

[Jayefuu]

The tilt switch was this one from Maplin. It was £1.89. You could get similar switches from loads of retailers. If you find one you think is suitable but aren't sure, message me with a link and I'll check it before you buy.

[ripstik juggler]

this is truly briliant... i know how to record an evil screeching noise and i used that instead of laughing. my brother just about p****ed himself when he tried to take a drink [=

[nerd12]

[Jayefuu]

Ha ha. Make one! Then post pics/video and I'll give you a patch.

Glad you like it! Please vote =]

[porcupinemamma]

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.

[Jayefuu]

He he. I want to learn to do more of the project on here. Especially some of the woodworking ones. Need more tools! The vote button is at the top, to the right or the Art of Sound contest banner. Thanks

[porcupinemamma]

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.
