- This device can make your very own tornado in a bottle. One of the most classic science experiments of our time.
- Use this device with two 2L pop bottles (preferably clear). Fill one of the plastic bottles with water, attach them at the center with the tornado tube and watch a tornado of water rush from the top bottle down through the connection to the lower bottle.
The science behind it:
The vortex in this experiment is created when gravity pulls a liquid through an opening to form a rotating tornado. Swirling the water in a bottle while pouring it out causes the formation of a vortex, making it easier for air to come into the bottle and allows the water to pour out faster.
