Everybody knows by now that mixing mentos into coke will cause a huge reaction and a big mess when it happens. This effect is instantaneous therefore it’s hard to prank someone else without getting yourself in the mess as well. So how do you pull off this prank without getting yourself wet? Here’s the answer:

 coca-cola mentos time delay prank

Simply by freezing mentos in watered ice cube trays and dumping them into coke, the gushing reaction can be delayed long enough for you and your partners to get away from the victim. When the ice layer melts for the coke to touch the surface of the mints, you can then spend some quality time to laugh from afar!
