You’re likely familiar with Newton’s cradle, a common desk toy that shows the conservation of momentum with a set of swinging balls.
Yasutoki Kariya took this idea one step further with a mesmerizing display called Asobi, replacing the metal balls with working light bulbs, My Modern Met reports.
As you can see in the video above, the light bulbs visualize the physics behind Newton’s cradle, which in case you need a refresher dictates that for every action there is always an equal and opposite reaction. The blog explains (rather eloquently):
The traveling speck of light that shoots across the stationary bulbs in the center and bursts into a bright spark of luminescence at the ends seems to inexplicably fulfill the audience’s visual desires. The senses are ignited at each end and ready to experience that next jolt of lightning in the bulb on the opposite end of the structure.
