Start-Up Circuits from MindWare are a fun way to teach your child the abstract concept of circuitry. The switch blocks and action tops are easy to snap together and the buttons are the perfect size for little fingers. Your curious child can mix and match the switch blocks and light-up, fan, and noise-making tops simply by snapping them together. When the red line makes a continuous path across a switch block and action top, completing the circuit, and the switch is pressed or pushed, the Start-Up Circuit springs into action.

Ages 18 months and up 

Contains
3 different action tops that light up, whistle and whirl.
