This is a totally awesome example of how science and nature are bound together. The only things needed for this demonstration is a pool and a plate, and you’ll have something amazing. This would be a great science lesson lesson to teach your kids.
When she moves the plate in the water, watch what happens at the bottom of the pool. At first it’s hard to tell what’s actually going on, what they are is actually two small vortexes that are traveling together through the water. Watch the video to find out exactly why.
