Throughout all my years of studying science, and more specifically physics, I have seen some pretty cool science demos. In Mr. Kennedy’s class, I saw Group I elements ignite when exposed to water. In Mr. Keenan’s class, I saw a cinder block broken over someone laying down on a bed of nails. In Dr. Spalding’s class, I viewed really tiny objects using an AFM and an SEM. In all those years, however, I had never come across the Rubens Tube, until today. Here are a couple of YouTube videos to demonstrate the tube:
