This cool vortex valve tornado tube is designed to demonstrate how a tornado is created.

Simply choose two large soft drink bottles of the same size, fill one with water, then connect them together with the special Tornado Tube Vortex Valve. With a flick of the wrist you'll create a tornado in a bottle!

It's great scientific fun. Add food colouring to the water for an even cooler effect!

Also available in a classroom 25 pack.

Please note: As this is a water activity, it is best done outside or over a science bench. If you experience leakage, please try using cling wrap around the bottle thread - not over the top. It is normal to experience a small amount of water on the outside depending on the bottles used.

Gave this to my 10 year old grandson, he loved it as did many of the other kids and adults at his party. It sure was a hit.

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.

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.

The mist lamps I bought for presents are totally mesmerising. The colours are soft and very pretty. The mist rising and swirling is really calming. Postage was quick and packaging was secure. CoolThings is a great site for gifts. I'll be back....
