Growing seedlings at less than 1 G

Article Abstract:

Amateur scientists can study the growth of plants between 0 G and 1 G by making a clinostat out of a bicycle wheel and frame. A clinostat makes plants feel as if they are growing in near-zero gravity conditions. Plants grow straight at 1 G, but crooked at close to 0 G.
