Makey Makey kits turn everyday objects into computer input touchpads, so a banana becomes the space bar. It's a simple invention kit for beginners and experts doing art, engineering, and everything in between.
The kits come with a board that looks like a classic Nintendo controller and a collection of clips and wires to connect it to anything conductive.
Materials that work great: plants, coins, your grandma, silverware, anything that is wet, most foods, cats and dogs, aluminum foil, pencil lead, fruit, and hundreds more.
Play the piano on your friends' hands. Make a drum set out of coins. Control Mario by stepping on foil squares.
