Mentos and Diet Coke.... Put them together and they make one of the coolest backyard science experiments ever discovered!

This small gadget, Steve Spangler's Geyser Tube to be exact, is a world-wide internet sensation that allows you to carry out a cool experiment, and to maximise the effects!

Simply load a packet of Mentos chewy mints into the screw-on transparent tube, lock it into your 2 litre bottle of diet coke (any aerated drink will do, but diet cola achieves the best result), and pull the pin!

And you guessed it, RUN!

The moment the chewy mints hit the liquid, a spectacular and powerful soda geyser explodes from the top of the bottle with enough pressure to reach up to 30 feet!

And thanks to this creative little gadget you'll get a perfect lift-off every time without getting drenched!

All necessary instructions for a successful launch are included. Educational information on how the eruption occurs is also included.

The Geyser Tube is 16 cm in length and recommended for ages 8+.

Have not done this trick for a long time, and my grandson’s birthday started with the bang it deserved. He just loved it and I would recommend this good ‘clean’ fun to anyone.

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....
