Flash Bomb

Like fart spray/stink bomb/who me, chlorine/tear gas, mace, and bug spray, this item is thrown mainly to scare people and releases air. Unlike these items, this one will make a flash. It has to hit something such as an NPC, or the wall hard enough to release an explosion that blasts air upwards. The explosion is very small and kills people when on them. It doesn't destroy topsoil but destroys the soil under.
