These cool tornado tubes are designed to demonstrate how a tornado is created and are also awesome for building bottle rockets.

For the water tornado effect you simply choose two large soft drink bottles of the same size, fill one with water, then connect them together with the special Tornado Tube. 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!

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 thread and poke a hole through the middle. It is normal to experience a small amount of water on the outside depending on the bottles used.

The children have been having lots of fun with the Vortex valve tornado tubes, seeing who can create the biggest tornado.

I recently purchased a number of items for giving at Christmas. It is premature to ask me to review them at this stage! Last December I furnished you with an enthusiastic review for the zip string laser, which I note is still promoting the product. It was done with goodwill and authenticity (but did not, alas, impress sufficiently to earn the $50 v...
