Japanese art student Yasutoki Kariya has reimagined Newton's Cradle using 11 computer-programmed incandescent light bulbs, some string and a motor.
You might remember Newton's Cradle from the desktops of bored bosses everywhere. It was named after Sir Isaac Newton to illustrate his third law of motion: the five-ball Cradle shows that for every action there is a equal and opposite reaction.
Kariya has taken the concept, swapped the metal balls with light globes and reproduced the energy created by their force using pistons. It's called "Asobi" and watching it is a little bit whimsical, a little bit scientific and – thankfully – far away from your boss's office.
