Astounding self siphoning beads experiment

In the video these beads seem to levitate, defy gravity and jump out of the beaker. But how and why do they act like this? Steve Mould, the science guy from Britain’s Brightest, explains the science behind the “self siphoning beads” – also known as “Newton’s Beads.”

“To get a closer look at the phenomenon, we filmed them in slow motion to try to work out what exactly was happening, and how the behavior changes with height.”
