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.

Jacob K. ★★★★★

My kids were mesmerized watching the water spin into a funnel shape—it's such a simple but effective connector. The tube fits standard soda bottles perfectly and creates a really impressive vortex every time.

Avery B. ★★★★★

Made a tornado in about 10 seconds with just two soda bottles and this tube – the connector seals tight enough that not a drop leaked. My kids have been mesmerized for days now.

Charlotte ★★★★☆

Took a few tries to get the bottle connection watertight, but once we did the spinning vortex effect was surprisingly dramatic. Works exactly as described for a quick science demo.
