We werebig fan of the video of that flaky bead - chain of mountains experimentthat made the rounds on the internet this summertime , but not quite as big fans as John Biggins and Mark Warner , physicists from Cambridge University who have published a journal clause explaining just what ’s fit on in the viral picture .
This is the bead - concatenation experiment . It ’s about to melt your mental capacity .
Inthe television fromthe BBC ’s Steve Mould , beads seem to move themselves right up and out of a beaker in a exclusive chain . So just what ’s going on ? Biggins and Warner took a looking at at the physics of the problem , and establish that there are actually a pretty complex set of forces causing the different apparent movement the chain is making .
They made this video explain just what force are acting on the mountain chain at unlike tip in its cycle of drift . you could also read their whole newspaper , published in Proceedings of the Royal Academy A , here .
