I was thinking more along the lines of taping or stringing a bunch of mentos together, and attaching it to the inside of the bottle cap. Lower them into the bottle(make sure level of Pepsi is lower than Mentos) and twist the cap. Then, either tip the bottle over, throw the bottle, drop the bottle from a building.....

Problem is that, as you can see in the video, the reaction is much too quick for you to even have time to twist the cap.
