Following up on our rubber band-powered boat, we made a dancing pill bottle. We drilled a hole in the top of a pill bottle. Then we put a rubber band around a popsicle stick and stuck the rest of the rubber band through the hole in the cap. We wrapped the other end of the rubber band around the bottom of the bottle and put the cap on the bottle. Finally, we spun the popsicle stick around to wind up the rubber band. I was hoping we might get a little helicopter-like lift out of it, but instead, it made the bottle dance around - still pretty neat.
