Stylish exec' office toy
Playing merry hell with the laws of thermodynamics, the seemingly perpetual motion of Perpendum
is enough to baffle any boffin. Most recently seen distracting Tony Stark in Iron Man 2
, this playfully-cartwheeling kinetic sculpture
is actually powered by 4 AA batteries. Even so, set the sticks a-spinning and they won’t stop twirling for three whole years
How on earth does this work? Well, Perpendum has been expertly calibrated so that the tiniest amount of power will keep the precision-engineered arms turning. What’s more, there’s no way to predict which way they’ll move – making this simple sculpture a truly hypnotic little toy.
