Needle and Thread
2 litre diet coke
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....
