Ending1: [step] Be sure to make the wick long enough for someone to be able to get away in time. [title] Fill the grenade with some inexpensive or cheap 6 mm plastic bbs. Ending2: [title] Blow air into the skin where you pulled in the firecracker. [step] Later, polish it with black paint; again, a nice' revenge'. Ending3: [step] You may want to do this test testing in front of a rabbit so that you see what happens.

Ending4: [title] Keep on cutting all the way around so that the air is all out of the container. [title] Take out the tex-mex balloon (optional) and be creative here with the timing.
