   Stop and look

   Stop and hold it still. Watch the middle. A skinny funnel forms and the glitter spins around it.

   Talk about why

   Spinning water gets flung toward the sides of the jar. That leaves a low spot in the middle, which is the funnel. Real tornadoes spin the same way, with air instead of water.
