A large diet pop, it needs to be diet but I don't know why, and seven mentos.
Do this outside only or you will be repainting your ceilings. Drop the seven mentos into the pop.
Start running so you don't get hit. The kids and I watched from the deck. Call us wimps if you want but that was close enough for us. My excuse was I wanted to take pictures so I guess you could call the kids wimps.
About two and a half seconds later the whole thing is over.
This is how much was left in the bottle. Impressive. The thought is that the mints release something that changes the nature of the pop and accelerates the formation of carbon-dioxide bubbles. Also, thousands of tiny pits are exposed on the surface of the mints making the perfect places for bubbles to form. The mints sink to the bottom of the bottle and the bubbles blast the pop out at a high velocity. This is just a guess, supposedly no one knows why this works. Why did someone try it in the first place?
