Bomb is a powder element in Powder Game. It is the second heaviest element, the first being mercury. It acts as a bomb, exploding on contact with any of the other elements, except for fan and clone. When it detonates, there is "shrapnel" from the bomb scattered and then it disappears or changes into another element. Bomb does not sink or float, due to the fact that it explodes on contact with most elements. Different elements react differently upon contact with it, but they all simulate explosions.
