ABSTRACT:
This invention is a multi-stable mechanical device. It is a bundle of rods surrounded by elastic, which when manipulated can be made to change from one stable close-packed state to another, causing a sudden rearrangement of the rods within the bundle, and producing a snapping noise or click which can be heard and felt with the fingers, and interesting visual effects due to the rearrangement of the rods. Possible applications of this invention are amusement devices, puzzles, science education, toys, executive pacifiers, hand exercisers, and physics and materials science demonstrations.
