In this activity you will make your own tornado in a bottle. Safety PET bottles used by younger children should have their plastic rings removed Procedure Make sure that the plastic rings are removed from the necks of the bottles.
Half fill one bottle with water.
Dry the opening of the bottle with paper towel then place the washer over it. Place the second bottle upside down on top of the washer. Carefully secure the bottles together with tape. Turn the bottles upside down so that the bottle containing the water is on top. Observe what happens.
