Hurricane 1

---

By Amanda

MATERIALS NEEDED
1 straw
1 glass
Water

PROCEDURE
1. Fill the glass with water.
2. Make a cut in the mid-point of the straw.
3. Put the straw in the glass.
4. Blow into the straw.

RESULT
The water is pushed out of the cut in the straw.

WHY?
When your breath exits through the cut in the straw, the pressure at the bottom half of the straw is lessened. The swirling water is what happens in the real hurricane, when the wind flows from the surface to the upper atmosphere.
