A mento put in a potion bottle of Coca-Cola (Coca-Cola espuma BOOOOOM! cold Coca-Cola bottle, bruh; I do suspect they froze the bottle before the mentos). This experiment, you see on-screen, failed because the mentos box was opened and not moved away (it contains all those Mentos), but it still does not change that 1 mento was put in. The safety cap dissolved before he put it in. LoL. this will will start a Coca-Cola tsunami
