Diet Coke and Mentos Prank

So today I will show you guys how to make a cool prank with diet coke and mentos, so if your mom or dad or grandparents or anyone you know like to drink diet coke, this prank is for you.

Materials:

One of the Giant bottles of diet coke(like 2 liters or something)

A needle and thread

Mentos

So now you want to take your needle and thread, and your mento, and stick the needle through the center of the mento, then disconnect the thread from the needle and tie a GOOD knot so the thread can't get out.

So know you take your bottle of diet coke and you lower the mento(still on the string) into the coke. Now don't let go, but screw the lid on so the lid is holding the string. Now cut off most of the excess string so you can barely tell, and Voila! You are done! next time someone opens the coke bottle, the lid will release the string and drop the mento into the coke, and BOOM! Big coke explosion.
