Bouncy Plastic Spring

I got bored of smacking metal pots, so I crawled over behind the television stand to find something weird! There was this rainbow plastic coiled thing sitting right in a plastic storage bin! I grabbed one end and yanked it so hard it stretched all the way across the floor like a giant snake! Then—SNAP!—it bounced right back and bopped me directly on the shin! Whoa! It didn't make a loud clang, but it jiggled back and forth like crazy! I ended up wrapping half of the bouncy coils around my waist and stomping in circles to watch it wobble!
