I got a usefull tip for all of you that drinks soda from a plastic bottle: I guess you are tired of the soda spilling all over the place when you open the bottle. Well I got a tip, and haven't have this problem since Just put one hand UNDER the bottle while unscrewing with the other hand and you should never have this problem again! This might not work if you shake the bottle like a maniac excactly before you open it, though I haven't tried that. Tell me if it works!!!
