I want to pull a prank but I just can't think of any!!! Argh!!!
I've got the perfect prank. things you will need:
Bottle of diet coke Mentos Floss something sharp-ish.
Take off the cap of the diet coke, then take the sharp object and make a hole in the mento. Then thread the floss through and put the mento over the opening of the full diet coke bottle. MAKE SURE THE MENTO DOES NOT DROP IN. Then screw the cap back on the bottle with the mento hanging overtop of the bottle inside the cap. Clip the access floss away with scissors.
When someone goes to open it, the mento will drop it and the pop will go all over them :)

Just ask somebody or just search in the web!
