Screaming Balloons

No, it’s not a mistake. Clear balloons belong in the sound section because of an amazing discovery we made. Normally, we would tell you to put a penny inside the latex balloon and blow it up. Hold the balloon with both hands and make a swirling motion. Thanks to the laws of inertia and some centripetal motion, the penny flips up on its edge and spins around the inside of the balloon. However, try substituting one of our hex nuts for the penny and you get a screaming balloon! The unique shape of the hex nut vibrates the walls of the balloon to produce wonderfully annoying sound. Just imagine the fun you’ll have with a classroom full of screaming balloons.
