Who doesn’t love the Back to the Future series and who could forget Marty’s hoverboard? Now you can build your own desktop version using electromagnets and a hoverboard prop. It can only support 5 pounds, but still looks pretty spectacular. Mattel is actually going to start selling replicas of the boards this holiday season (but you can also buy them on eBay) so you can build your own using the instructions.
For even more electromagnetics fun, check out our colllection of electromagnetism projects below. We even have versions which use Arduino!
