Circuit Blox™ BYO Disco Volante Blocchi da Costruzione per Circuiti

The LEDs actually light up when my son snaps the blocks together in the right order, and he's been rebuilding the flying saucer three different ways all afternoon. Took him a bit to get the circuit right the first time, but once it clicked he wouldn't put it down.

My daughter figured out how to swap the blocks so the little fan actually spins, and she's been rebuilding it into different shapes all afternoon. The components click together firmly, so it doesn't fall apart when she carries it around.

We've had this kit for two weeks and the LEDs still get a wow out of my kids every time they snap a circuit together right. The blocks feel sturdy enough to survive being shoved back in the bin, and I like that they're actually learning how a circuit works instead of just watching lights blink.
