Description The B.B. is essentially a wooden hamster wheel - changed into a cage. With force one can put dust bunnies and Borstels into the Cage. The axis is made of metal, coated with balloonskin. By turning the wheel really fast (if the Borstels sulk and don't run by themselves), the static energy of all the hair will be transferred into the end. Do not forget to attach empty, renewable batteries on the ends. The more conventional method is the Balloon Battery.
