The Geyser Tube is a loading tube for the now-famous Diet Coke geyser powered by Mentos®. If you've ever tried doing the experiment, you know how difficult it can be to drop the Mentos® into the bottle before the reaction takes off... and you're soaking wet. The Geyser Tube will give you a perfect launch every time with time to stand back.

Easy to use: Attach the Geyser Tube to any bottle of soda (diet soda works best because it's not sticky - no sugar!). Secure the trigger pin in place. Load the Mentos® into the tube, lock the special pressurizing nozzle in place and pull the pin.

Oh, by the way, it's best to pull the pin and then run away. The string on the pin allows you to pull the pin from a distance (if you're concerned about getting wet!) The Mentos® drop into the bottle and the powerful soda geyser comes shooting out the top with enough pressure to reach an incredible height of 30 feet.

If you've never tried this amazing soda experiment, the Geyser Tube will give you a perfect launch every time. If you're a Mentos® geyser pro, you'll quickly see how to use this device to make the most out of this cool science demo.
