With this device, you can make your very own tornado in a bottle. One of the most classic science experiments of our time. All you need is this device and 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.
