Tornado Maker


Out of stock


Simple yet very entertaining, create a vortex using two plastic drinks bottles and this specially designed lid. Just screw the lid on top of a bottle filled with water, screw on a second empty bottle and turn them over, adding a bit of spin of you like, to see a brilliant water vortex form. We also suspect that this lid might work to amp up the famous mentos diet coke experiment, though we're yet to test it (we'll keep you posted). SUITABLE FOR CHILDREN AGED 5 YEARS AND UP.
