Launch a 25 foot soda geyser!!!
Steve Spangler’s original Geyser Tube launched an internet sensation back in 2005. Now his new and improved tube triggers an enormous soda geyser that flies 30% higher using only two Mentos Mints! It’s the perfect combination of science, exploration and fun!
How does it work?
Each Mentos has thousands of tiny pits on the surface called nucleation sites – perfect places for carbon dioxide bubbles already in the soda to form. As soon as the Mentos hit the soda, bubbles form all over the chewy mints and then quickly rise to the surface of the liquid. Couple this with the fact that the Mentos are heavy and sink to the bottom of the bottle and you’ve got a double-whammy. When all this gas is released, it literally pushes all the liquid up and out of the bottle in an incredible soda blast.
Please DO NOT EAT the Mentos contained in the packaging, they are for the experiment only. For ages 8 year up.
Not suitable for children under three years old, keep out of their reach.
