How do you make a diet pepsi bomb without Mentos?

Items needed:

Diet Coke (not a can, must be in a bottle. The large bottle is reccomended for this type of bomb)

String (at least 3-6 inches, not too strong)

A lot of Mentos (the more diet coke, the more mentos)

What to do: Take the cap off of a new bottle, and tie the mento pieces to string. 3 mentos would be a good amount for a big bottle (not 100% sure, and more for the bomb). Then take them and put them inside the bottle NOT touching the coke AT ALL (if you have to relax and take a sip it won't bite xD). Then close it, and choose 1 of 2 options:

Coke Cannon: Close the diet coke tightly, and either attack someone with it (for fun) or just make a fountain. Shake the bottle some so it is ready then aim it to where you want it to explode (not completely up though). Loosen the cap and BOOM.

Coke Bomb: Tape the top part of the bottle, and wait for when you want to use it. Shake it, lay it down and run.
