When kids click together these Chunky pieces and then flip a switch, they'll get an exciting result: Either a spinning fan, a glowing light, or a whistling siren! All switch blocks and action tops are interchangeable for mixing, matching, and experimenting with actual working circuits in a completely safe way. Young children will develop an innate understanding of circuitry and build a strong foundation for future STEM success. These actions support Cause/Effect understanding and Finger/Hand coordination and control. Includes 3 switch blocks, 3 action tops, instructions, and parent guide. Requires 6 AA batteries (not included).
Appropriate for ages 2 through 6.
