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!!!!!!!!

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

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

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

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

    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

    Wow, quite a few spaces, i thought my browser stopped loading the page :P -gamer
