Great Scott! These Back to the Future DIY projects are sure to knock your socks off. (And maybe even your self-drying jacket.)

Who didn’t want Marty McFly’s sweet hoverboard (at least until he got stuck over the water)? Now you can make your own replica. And no need to wait around a parking lot for black-market plutonium — you can make these flux capacitors with components you have laying around the house.

Where you’re going, you might not need roads, but DIY project inspiration is always welcome, no matter what decade you happen to be in.
