Let science come to life with the Vortex Valve Tornado Tube! With just a flick of the wrist, an impressive tornado in a bottle is created.

You can create and harness a tornado by using a full bottle of water and then connecting it to another empty bottle of the same size with our special Tornado Tube Vortex Valve.

Flip and flick the bottles for instant tornado action!

You can even add food colouring, detergent (for bubbles) and/or different oils to the water for even cooler effects.

Now supplied with two ‘0-ring’ seals to protect against leakage.

Please note:

  • Water activities can get tricky, so it helps to be outside before starting (or over a science bench/sink/wet area). If you experience leakage, try wrapping some cling wrap around the threads of the bottles.
  • It is normal to experience a small amount of water on the outside, depending on the bottles used.

Cool science fun for ages 5 and up!

Comes in 4 different colours, either Red, Blue, Purple or Yellow - chosen at random

Spin into the fun and fascination of fluid dynamics with the hands-on Vortex Valve Tornado Tube!

So simple to use

We played with this the day we got the package. Followed the instructions and I got to lecture the kids on science and how great it was. They responded by ignoring me and going off the make more tornados! Small, but fun.

Great connectors

I've had these tornado tube valves before (from another supplier), and these were a replacement. I was definitely happy, as these came with 'O' rings to prevent leakage, which has always been a problem in the past.

My daughters project was due in 5 days and we ordered from cool things and it came extra quick for us within 48hrs, other kids projects were leaking but not my daughters.. the team at cool things supplied rubber stoppers to stop leaks from the bottles.. her project was a stand out and received an A grade :) Thanks cool things!
