Did anybody see the Coca Cola/Mentos one, where they shot the Coke 23 ft. in the air? That was a riot. My hubby & bil tried it & it works! Doesn't work with pepsi, but if you put a few mentos in your mouth & drink Coke it will come exploding out of your mouth! It was rather amusing watching those two goof balls out there trying it!
The also dropped a couple mentos in 20 oz cokes & it would explode so fast they didn't have time to put the cap back on. Pretty wild!
