In this video clip, a young lady attempts to make a condom rocket powered by Mentos and Diet Coke. For those of you who haven’t seen any of the countless videos from this award winning phenomenon, it produces something similar to a geyser.

The concept makes sense, and should be pretty easy to accomplish, right? She seems certain that it will work, and shows how to do it step by step. But things don’t turn out exactly as planned.

Instead of a rocket, the unsuspecting girl ends up with an exploding Diet Coke filled condom. Not quite the effect she was going for, but pretty darn funny anyway.
