Make magic jumping beans

We were dumbfounded at first, too. But this jumping bean is momentum based, not larva powered.

The erratic movement of these DIY foil toys is actually simple physics. Hint: there is a marble inside the aluminum foil. When the marble rolls internally to the foil's end, the foil-bean flips with the momentum. All this commotion mixed with some well coached hands makes for a magic jumping effect.

Mexican jumping beans on the other hand are a native biological phenomenon. The jumping beans are actually seeds in which a moth has laid eggs. When the eggs hatch the larva's movement makes the beans bounce about.

We recommend either beans as perfect toys for cats or a small child.
