Step 3: Step 3.
Step 4: Overview
second don't breath smoke if you do happen to have a smoke grenade (it probably will give you cancer, everything else does)
third don't play with grenades (again) but if you must then pull and drop the pin, throw the grenade. (I only say this because it happened to a new guy)
don't do anything stupid or dangerous and then say i taught you how to do it.
