How to make an airsoft grenade
Open a regular plastic easter egg.
Drill or cut out the little hole in the bottom.
Insert a firecracker (types may vary), and stick the wick out of the hole (m90's are cheap, small, and very powerful).

OUT:
Be sure to make the wick long enough for someone to be able to get away in time. Fill the grenade with some inexpensive or cheap 6 mm plastic bbs.
