In Mexico grow brinkadores - jumping beans

Outwardly, they look like yellow-brown or brown beans. They are a kind of seed, in which lay their larvae are small moths. It is these larvae make beans "jump».

If warm bean, for example, by holding it in your hand, then the larva inside starts to decline, forcing Bob to move. The word "jump" in this case is an exaggeration, but the beans really far from a state of rest.

Suitable only beans with a slight greenish tinge. If Bob is completely brown, it is likely he was "dead." If you podnesёte bean close to his ear, shake it, and shaking will hear a rustling inside, the larvae of moths is dead, so the bean is also not suitable.

"Bouncing" bean is a measure of survival - the larvae are afraid of the heat. They move to get away from the heat, as it leads them to dehydration and can kill. The ultraviolet rays of the sun also leads to the fact that the beans begin to move.
