The making of a small explosive with shrapnel, made by taking a small, depleted CO2 cartridge, widening the neck opening with a nail and filling it with black powder while tapping it LIGHTLY. A green fuse is then placed into the neck. If constructed correctly, it can have an explosion the size of an M80 or bigger, with shrapnel.
You man, we couldn't find any M80s for old lady Pfifers mailbox, so we made some cartridge bombs!
