You need:

Needle and Thread
2 litre diet coke
a mento

First thread the needle
This is hard for most people for some reason

Step 1: Through the Mento

Just thread the needle through the mento ( or mentos) and tie a GOOD knot

Now cut the thread on one side short and the other 1 foot.

Step 2: Rig It!

Now lower the mento into the bottle just a little bit and put the string out of the bottle, now close the lid. if it worked the mento should be dangling there. now cut the string and wait....

done yet?


You're grounded!!!!!!!!

    diet coke taste the same so yea

    nope! i've even used normal 7 up! it dose not work quite as well without the aspartame, but it still works!

    Asparatame gives you a better chance of getting cancer :(

    no its coke and mentos how will you get cancer

    Urban legend. No clinical evidence to back this up.

    It's been tested. It is true

    you are Right,,, a railroad carful will cause cancer in rats!!!!!!!!!!!!!!!!!!!!

    ooooooooooOOoooooo. So that is why diet soda can give you cancer

    Read the label. In the ingredients look for "aspartame". If it has aspartame you can get cancer from having too much

    Aspartame also eats holes in your brains. .. .. Yes, your brains.

    Sounds delightful xD I am very dissapointed.. I was at my friends house. And all he had was diet soda... So I had to.

    Thanx Man, now I can prank my Coke lovin' uncle!

    what I would suggest doing is offerring him a drink while hes outside, then bringing him the rigged coke and a glass, that way the mess is outside, and you garantee you get to see it.


    this is really cool i want to try it
