Create amazing cosmic sound effects! The Zube Tube is simple in concept; an acoustic coil is stretched between two plastic resonators inserted into the of a tube. Vibrations on the coil travel back and forth along the coil creating sound. Kids of all ages will enjoy creating various sounds by shaking and twisting the tube, plucking the coil, tapping the tube, speaking into the resonator, cupping a hand over the end of the tube...the possibilities are endless! Careful--once you pick it up, it's hard to put it down! Ages 3 & up.
