Makey Makey Classic

Makey Makey Classic is a circuit board that connects everyday objects to a computer as keyboard and mouse inputs. Clip an alligator wire to anything that conducts (fruit, foil, graphite, a friend's hand) and it becomes a touchpad. No drivers, no app, no coding. The board handles up to 18 inputs with multi-key remapping and works with any device that accepts a USB keyboard. Includes the board, USB cable, seven alligator clips, and six connector wires. Ages 8 and up.

It teaches one idea that sticks: a computer input is just a circuit you can close with almost anything. First setup is a banana piano in seconds, and an hour later they've wired a game controller out of Play-Doh. Works on any Mac, Windows, or Chromebook with nothing to install.
