Have you ever dropped a Mentos (the fresh maker!) candy into a bottle of Coca-Cola? Have you ever wondered what would happen if you could somehow manage to put an entire package's worth of Mentos candy into a bottle of Coca-Cola before the soda fizzed out of control?
Wonder no longer. This Italian man, with the assistance of a single Durex condom and what looks like painter's tape, accomplishes the feat.
N.B. to men: Once you've seen this video, you might never again feel adequate when using a condom. (Though you might feel more confident in a condom's efficacy.)
