A Scientific Phenomenon Occurs When You Use a Plate to Create a Ripple Effect in a Pool

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.

As explained in the video, the black circles are actually a shadow of two vortexes created by the action of moving the plate through the water.
