Inside the Mexican jumping bean is a little moth caterpillar.
When the Mexican Jumping Bean jumps, it is because a moth larvae inside is moving around in it.
The Mexican jumping bean is not a bean at all but a seed capsule from the Mexican shrub Sebastiana pavoniana. Inside the seed there is a small larva or worm of the Laspeyresia Saltitansmoth. When it feels warm temperatures, it begins to twitch, thus making the bean to appear it is "jumping". Eventually, the moth will hatch, and you will see the small creature leaving the seed.

They jump because there is a moth larvae inside them. The moth lays its eggs in the flower, and the larvae then grow inside the bean, and eat the center out. They live there inside the bean and when they move, the bean moves. A benefit to the bean jumping is that when a bird is hungry it might want to eat the bean, but when it sees it jumping, it scares the bird. Then later they turn into moths that come out of the bean.

The scientific answer is no-no it cannot drown,but if it is in the process of emerging and it gets in deep water besides just a tiny mist,then yes it will drown

Yes, there is no such thing as a "human Bean" Mexican jumping bean maybe.
If they don't jump at all for a while then there dead
Theu emerge in May. It takes almost a year for them to come out from their "bean".
Usually they react to heat. If they are put in the sun or somewhere warm, they start jumping. Being it's a worm inside the bean, the heat gets it going.
the thing is jumping beans dont do jumping jacks and the reason they jump is that inside the bean there is a silkworm and soon the silkworm will stop moving so the bean will stop moving it is not dead its just dormant, and eventually a cacoon will come out of the bean and in a matter of seconds a moth will come out of the cacoon.
