The Mushroom Cloud is named after the image of the cloud of dust after an Atomic Bomb detonates. It is generally large, with a greyish color. It may be yellow or black depending on the time when the explosion is seen. It carries radiation fallout and is extremely dangerous. It may be seen with a ring around it, however how the ring is formed is still a mystery. Some people have suspected that the Mushroom Cloud looks that way because the Nuclear Explosion compresses the matter until the top, where the thinner air and far from the explosion site causes it to scatter and drop.
