These beads seem to levitate, defy gravity and jump out of the beaker. But how and why do they act like this? If you click on the link at the end of this short video you can find another video giving an explanation. Steve Mould, the science guy from Britain’s Brightest, explores the science behind the “self siphoning beads” – also known as “Newton’s Beads”.
The second video films them in slow motion to try to work out what exactly was happening, and how the behaviour changes with height.
