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!


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


- 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.
you should include a video
Adds a completely new meaning to "canned laughter"
lol <br>
try&nbsp; Pedobear-style Laughter.... or pedo seal, or pedo cat, or pedodog or pedofish.... pedo-tato, anyone?<br />
You should put something that vibrates on it instead of something to make sound.&nbsp; That way, it spills all over them!
you know i did that except i rigged it to say hehehheheheheheheheh and it was a bash<br />
I showed my cousin this and he did it on me when I&nbsp;was unsuspecting, switched my coke can for his when I took a piss. I&nbsp;nearly had a heart attack!<br /> <br /> <br /> <br /> P.S. Why do you &quot;take a piss&quot; when you are giving the toilet your piss?
you have exactly same computer table as me lol
It didn't look so heavy before I decided to carry it back from B&Q! I was :(
i see you're from UK.....<br /> first maplin, then b&amp;q<br />
oo i got it from ikea tho..ya its heavy!
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.
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!
Glad I could help.
it would also save up on the battery...<br />
yay, tilt switch came in, ive soldered it, and hot glued it to a 7up can :D<br /> its now waiting in the fridge for a helpless victim XD<br /> <br /> gotta make a video of it in action soon, free patch for me :D<br />
Definitely! And will include it in the last step with your permission if you get one :)<br />
sure!<br /> well, maybe not if the victim doesnt want to &gt;.&lt;<br /> and maybe u wont understand a bit of what would be said, since were all dutch...<br /> <br /> the can is still in the fridge...<br /> we dont have soda that much, so if we have it we already kinda know its for somebody, so we dont take it :P<br /> maybe i should give it to someone, then il have the chance to video it to :P<br />
Did you get anyone?&nbsp;:D<br />
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)<br /> its mostly becouse its to light, so im gonna add something as a weight, and see if it works then...<br />
Oh boy, I think our goodwill has a tickle me elmo, but I know it has a chicken dance elmo!!!
what spicific laughing toy did you use and were did you get it and the tilt switch
alot of fast food stops have them
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.
thx didn't realize how many things make noise
The tilt switch was <a rel="nofollow" href="http://www.maplin.co.uk/Module.aspx?ModuleNo=10116">this</a> one from Maplin. It was &pound;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.<br/>
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 [=<br/>
this is an totally awesome prank id like to try it on my parents or sis but they don't drink, buy cans and i can't get all the meterials for this project. thanks though!
Thank you! Subscribe and vote please, I'll be adding more soon!
Very nice!keep up the good work
Thanks! Please vote if you haven't already!
I got something similar as a christmas present- it was a mug that played a christmas carol when lifted up. Instead of a tilt sensor, it used a light sensor on the bottom , which meant that it didn't always activated when lifted, making it even harder to find the source of the song.
my uncle had one of those, but we threw it away because every time it got washed the washing machine started playing jingle bells lol
Yeah eventually the compartment with the batteries and electronics got water in it and, well.... jingle bells playing constantly at 5x speed was enough to warrant chucking the freaking thing immediately out the window. Pedestrians be damned.
hahaha... merry f***ing christmas to whoever was unlucky enough to be walking under your window that day XD
its the cristmas carrol curse!
I thought of using a light dependant resistor, but it would have complicated the electronics, and gone off before they got a chance to get it near their mouth.
I want one1 ;0)
Ha ha. Make one! Then post pics/video and I'll give you a patch.<br/><br/>Glad you like it! Please vote =]<br/>
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.
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
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.
Ha, ha, ha this is great.
Thanks! Glad you like it. Please vote.
Already did.
Fix it up with some sort of water sprayer like a windshiled washer reservoir pump that will squirt out at them when they pick it up.
He he. I did a similar thing in <a rel="nofollow" href="http://www.instructables.com/id/Leaky-Coke-Can-Prank/">this</a> instructable. Water falls out the bottom onto your victim when they tilt the can.<br/>
I think you should make it so the can makes a VERY loud siren or a doorbell sound
