I tried to show this to my friends and put about a whole can of altiods in a bottle. The bottle didn't erupt, and we were really disappointed (probably because it was knockoff cola) , but the bottle became hard as rock after we put the cap on. We decided it would be a good idea to toss it in the air. The first couple of times we did it it bounced like 10 feet in the air. The third time I threw it like 20 feet into the air and when it hit the ground the bottle cap broke off and the bottle shot across the parking lot, probably 20+ MPH, and flew into the side of the apartment building where I live. Cola and foam exploded everywhere. We laughed for about 2 seconds, then decided it would be a better idea to get the hell out of there.
