Listen up, egg heads. You may recall from your own household experiments that dropping a mint into a bottle of soda causes the said liquid to react violently. Well, the Geyser Tube has been designed to maximise this reaction. Here's what you do: place the screw-on transparent Gesyer Tube on to a bottle of pop. Load the mints provided into the tube and, when you are in a safe place, pull the pin (counting to three is, of course, optional). The moment the mints drop into the drink a powerful soda geyser erupts from the top of the bottle and shoots up the tube.

The pressure is enough to send the fizzy drink 30 feet in the air. After a successful launch you may wish to celebrate with a drink. We suggest you buy a fresh bottle of pop at this point.
