What I’ve GotI’ve got a Makey Makey, which is essentially an Arduino which can be connected to various everyday objects, and if the circuit is completed (either by a person, water, any conductive medium) you can connect any function of your computer (making sounds, playing songs, etc) to a physical action. This device is a really cool way to teach kids and adults about electronics in a fun, accessible way, and makes science and engineering more enjoyable.
