The Bead Chain is designed for developing the concept of cause and effect. Slight movement of the beads will turn on a built-in music box. While the beads are in contact with the metal bar, the music continues to play. There is also a jack that allows a switch adapted toy to be plugged in, and activation of the beads will allow the attached toy to operate. Switch device. Requires 2 AA batteries; included. Includes user guide. Two-week loan period. | |
