It's time to get young scientists out of the classroom and into the fresh air as they create their own mini tornadoes in a bottle!

Vortex Valve Tornado Tubes are a great way to introduce your children to the science of vortex energy, and help them learn how air pressure and density can work together to create an incredible force of nature! Simply attach a soft drink bottle to either end of the valve tube, fill one bottle with water so it looks like an hour glass, and tip it upside down. Give it a swirl and bare witness to a spectacular tornado!

In this kit you will receive 12 x Vortex Valve Tornado Tube's, perfect for a small group, and even better as party bag fillers for your next science party!

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.

Colours chosen at random.
Recommended for ages 4 and up.

I first saw these at my sons preschool. I run a family daycare so I purchased some and they have provided hours of entertainment for the children. Little do they know they are actually learning at the same time! ! And a great sustainability activity too using old soft drink bottles!
