Magnificent Wave

We know when a bomb explodes, we get a mushroom, grey one. The bigger the explosion, the larger the mushroom. It chokes, if you try to eat it.

Have you ever wonder water can give you a mushroom too? Found this via Digg, the mushroom is quite big. Boy, run! no wait...swim fast! (if you can)

according to Wikipedia:

"A wave is a disturbance that propagates through space or spacetime, often transferring energy. While a mechanical wave exists in a medium (which on deformation is capable of producing elastic restoring forces), waves of electromagnetic radiation (and probably gravitational radiation) can travel through vacuum, that is, without a medium. Waves travel and transfer energy from one point to another, often with little or no permanent displacement of the particles of the medium (i.e. little or no associated mass transport); instead there are oscillations around almost fixed positions."

and:

"A mushroom is an above-ground fruiting body (that is, a spore-producing structure) of a fungus having a shaft and a cap. By extension, mushroom also designates the entire fungus producing the fruiting body of such appearance, the fungus consisting of a network (called the mycelium) of filaments or hyphae. In an even broader sense, mushroom is applied to any visible fungus, or especially the fruiting body of any fungus, with the mycelium usually hidden under bark, ground, rotten wood, leaves, and other surface matter. The basidiocarp is the spore-producing structure of a "true" mushroom, while a toadstool is a basidiocarp that is poisonous to eat."
