Tornado in a Bottle

What You Need:

• Two 2 liter bottles
• Tape (duct tape works best)
• Water
• Food coloring (optional)

Instructions:

1. Fill one of the bottles about 3/4 full of water. Add a drop or two of food coloring.
2. Put the empty bottle upside-down on top of the bottle filled with water.
3. Tape the mouthpieces together.
4. Flip the bottles over so the one filled with water is on top. Rotate the bottle on top in a circular motion until a tornado starts to form.
5. Set the bottles on the table and watch the tornado in action!
6. Have fun!
