You know all about Mentos and Diet Coke right? Together, 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 this 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 16cm in length.
Recommended for ages 8+
