When They Drop A Bag Of Balls On The Escalator, It’s Fascinating

Two young men enter an office building, one of them with a giant red bag slung over his shoulder. They approach an escalator, and when the coast is clear, they empty out the bags’ contents. A multitude of brightly colored toy balls spills out and they begin to climb the escalator. Once they reach the top, they begin their descent and the cycle continues. After what must have been a tedious cleanup, the gentlemen unload the bag again – this time from the top.

This little science experiment is a display of kinetic energy. According to HyperPhysics, kinetic energy is “an expression of the fact that a moving object can do work on anything it hits; it quantifies the amount of work the object could do as a result of its motion.”

This is a pretty neat video and we encourage you to check it out below to see what happens once the bag is emptied out. There are a few bystanders in the clip that stop to see what the fuss is about. What did you think? Leave us a comment and let us know.
