How to create a small Whirlpool

A whirlpool is a swirling body of water usually produced by ocean tides. The vast majority of whirlpools are not very powerful. Moving water steadily around the outside edge of a pool eventually causes a depression in the center, creating the whirlpool reaction. Try it with your friends in the pool to make a nice and fun whirlpool.
