Those tiny foam helicopters are nigh impossible to control; I broke one by crashing it into a bookcase last summer. A project at Make remedies this, and teaches you, reader, how to construct your own, easy-to-fly blimp of sorts. You’ll need two of those helicopters, wizzzzadrrrrry, something called a dowel and some actual skill. Having none, I’ll pass.
Best done while not fighting the spins.
