It's easier to understand what Makey Makey is by watching this video of it in action than by describing it, but I'll give it a shot. Makey Makey is a printed circuit board that you connect to any computer with a USB cable (included). You don't need to install any software. Your computer thinks Makey Makey is a keyboard. And it is a keyboard of sorts. But it doesn't use standard keys. Instead, you connect wires from Makey Makey to anything that conducts electricity: a piece of fruit, a bowl of water, a cup of soup, a scrap of aluminum foil, blobs of Play-Doh. When you touch the object with your finger, your computer will think you are pressing a key on a standard keyboard. You can assign the object to be a spacebar key, an arrow key, or a letter key. And you can connect several objects to Makey Makey at the same time, so that you can create game controllers, musical interfaces, and other button-controlled devices.
It might not sound like much fun, but the possibilities are endless, and Makey Makey's ease of use encourages quick-and-dirty experimentation. My 12-year-old was instantly transfixed by Makey Makey and she started making all sorts of things with it, including a drum machine triggered by apple slices, and a game controller out of a cardboard box and bits of foil.
Makey Makey also works with Scratch, the excellent kids' software development platform. Check out the Makey Makey games people have created using Scratch.
