Okay, now, we've all seen the videos, but if I really wanted to do the "2 Liter Diet Coke as the Space Shuttle Launchpad", any hints on How To? I'm talking about the guys who are holding the bottle over their head, throw it down on the ground, then the bottle goes flying, about 50 yards. My questions:

- Do I dump the whole pack of Mentos in?
- Do I (try and) put the cap back on?
