2 years & up. When kids click together these chunky pieces and then flip the switch, they'll get an exciting result: either a spinning fan, a glowing light, or a whistling siren. All switch blocks are interchangeable for mixing, matching, and experimenting with actual working circuits in a completely safe way. Young children will develop and innate understanding of circuitry and build a strong foundation for future STEM success.

Requires 6 AA batteries (not included).


  • 3 different action tops that light up, whistle, and whir
  • 3 different switch blocks to push, slide, and flip
