Unlike conventional inorganic metals in which electrons zip through a crystalline lattice, in organics electrons must hop from one molecule to another,
like pails of water being passed by a bucket brigade.
Simply place the tub on top
of a small table, chair or other short sturdy surface (
like a cooler), fill it up with about an inch
of water, cups,
pails and shovels, and let your little ones engage in some pouring, emptying and splashing fun.
