"I totally underestimated how cool this would be."

A video posted online this week is gaining attention for showing a scientific phenomenon that occurs when a ripple effect is created in a swimming pool using a plate.

After dragging a plate in the water, a pair of black circles form at the bottom of the pool and continue traveling until they reach the other side.
