Butterfly Balancing GameWhizzing through the wings of the butterfly, the two steel balls repeatedly cross their own paths. Slightly differing tracks geared to a special loop arrangement result in this game developing a momentum of its very own. Magnetic holds fixed to the ends of the two sensors ensures secure stowage of the balls. This balancing game is useful for fostering powers of concentration as well as for developing motor skills.
