We've been fans of littleBits for a while now, but the latest set is one that you'll want to add to your little ones' holiday lists ASAP. The littleBits Electronics Gizmos and Gadgets Kit ($200) is an exciting way to encourage little kids' interest in electronics. The new Lego-like kits come with 15 electronic blocks and extra parts like wheels, stickers, and more — everything kids need to make 12 projects from bubble machines and a spy box to remote control cars. And we mean everything, including the 9-volt battery! Along the way, the little inventors learn a thing or two about electronics without ever feeling like they're playing with an educational toy (not that there's anything wrong with those!). If your child has ever expressed interest in building and creating, this is a toy worth saving for!
