everyone remembers the exciting mentos-in-coke explosion videos that circulated a while back, right? (see why the experiment works)
now some clever person has thought of a way to harness this energy long enough to shock and surprise your friends (or enemies) when it releases! introducing the other manhattan project!
the trick is to freeze mentos inside ice cubes so that when the ice melts enough for the little candies to touch the coke in the glass, the carbon bubbles rapidly created on the candy surface form a fizzy explosion in your friend's glass!
admittedly, coke in a "manhattan" might make a pretty crappy drink, but that name is better than highball or cuba libre!
i'm curious if this works though. someone should test the method and record it! would the mentos be visible enough inside the ice cubes to cause suspicion from the potential victim?? i'm not so sure i would be comfortable with white things inside of the ice in my glass, but maybe i wouldnt notice.
