23. Rubber-band Airplane

Item #23. Remember those rubber-band powered balsa-wood airplanes from when you were a kid that you would wind and wind and wind and let loose, and then it would fly into your mom’s lamp because you flew it indoors when you knew you were not supposed to? Make one of those – but really, really big. As big as you are thinking. Yeah, like that, but make it twice that big.
