This device has fascinated literally hundreds of students in the schools I teach at. As such, it is a great little device for discussing pressure, ideal gasses, energy conservation, fluids and circular motion.

For bottle selection, you'll need 2 litre bottles.with the larger necks. I found these were more common in own-brand soda bottles or mineral water rather than branded soft drinks. Once you find them, put in some distilled (boiled and cooled) water and a bit of glitter and you have a long lasting desk-toy.

Someone noted that the bottles get "sucked in". This happens as the air inside the bottles warms and cools. The best thing to do is to shake the water to allow the temperature and pressure to change, then twist the bottles and let more air into the bottle.

The only real issue is that when spinning the water initially, if the user is a little over-zealous, the plastic does start to show stress fractures. Still five stars.... after all, it hasn't broken yet, despite the best efforts of the students.

The tube didn't fit the water bottles I bought and the water leaked. I plan on trying other bottles but haven't got round to it yet.

Great present for my autistic son. This is a brilliant sensory toy, its very interesting and relaxing. Great toy for a class learning about Tornado's, children and adults both love it. You can add glitter and food colouring for extra interest.

A simple and long lasting solution compared with plastic tubing and clips. Nice vibrant colour makes it look more appealing, especially to a younger audience.

The vortex created is of good quality and lasts quite a while. I took off one star for some minor leakage I have experienced, though that can be reduced by slightly reducing the amount of water in the bottle. I have only tried this with cheap lemonade bottles, might work better with sturdier bottles!

Does produce a great tornado for kids to watch. There is a bit of a knack to getting it going and kids do find it difficult, plus you really need 2 litre bottles otherwise the water has gone before you've seen anything and this makes it quite cumbersome. So best as a demo tool rather than as a toy.

Bought this to support a weather unit we were doing at school. Kids were fascinated by tornadoes and this provided a model that was a real talking point.

This item is a good visual tool / learning experience for all KS1 primary school children . It would help children to understand how a tornado ' looks ' and is also a fun and interesting activity .

It does what it says it does and the effect is quite awesome but i would attempt to make one yourself before spending money on this because it is little more than a bottle top with a hole in it.

Great item. Works perfectly too with two 1 litre sized bottles. Is also semi transparent which is a plus. I spent hours mesmerised making little tornados with this thing.
