Warm up by doing the following dance moves slowly before you try them quickly. This helps to prevent injury.
Put on a piece of music with a strong, fast, continuous beat.
Shift your weight forward to the balls of both feet. Don't lift your heels; just shift your weight.
Bring your knees together and stop them just short of knocking together. As you do this, your heels will rotate out.
Swing your knees out---your toes should rotate to point out, too.
Repeat the previous two movements rapidly, swinging your knees in and out while rotating your toes in and out at the same time. This is the percolator dance.
Embellish your percolator dance or adapt it to your own personal style---see the Tips section for ideas.
