Trap A Tornado Cool Science Experiment
In this fun and easy cool science experiment, we’re going to trap a tornado in a bottle.
- Two 2-liter plastic soda bottles
- Metal washer
- Duct tape
- Glitter, beads, food coloring
- Fill one of the bottles about three quarters of the way with water.
- Add any glitter, beads, and food coloring you want to the water. Be sure the beads are small enough to easily fit through the center of the washer.
- Center the washer over the mouth of the bottle with water.
- Now position the empty bottle upside down so its mouth is centered over the washer.
- Use the duct tape to secure the bottles together.
- Flip the bottles over so the empty one is on the bottom and observe what happens.
- Flip the bottles one more time, but this time give the bottles a swirl and observe what happens.
How it Works:
When the bottles are flipped and positioned directly above one another, the water has a difficult time transitioning from the top bottle into the bottom bottle. When you twirl the bottles, a vortex is created that allows for an easier exchange of water and air between the bottles.
Make This A Science Project:
Add small items to the water like Styrofoam beads. Add sugar or salt to the water. Use vegetable oil instead of water. Try different sized washers. Try different sized bottles.
