Yasutoki Kariya’s Take on Newton’s Cradle

Art student Yasutoki Kariya of Tokyo’s Musashino Art University designed this take on Newton’s Cradle—the ubiquitous desk accessory made of suspended steel spheres—for his senior thesis. Kariya’s project, Asobi (“Playing”), uses light bulbs and not metal, but nevertheless demonstrates Sir Isaac Newton’s third law of motion: for every action there is an equal and opposite reaction. With programmed light motion instead of kinetic energy providing the sensory entertainment, Kariya’s project is visual rather than physical.
