That's kinda funny...reminds me of something we did at my house when I still lived with my parents.
There's this video game we all used to play together on Wii called Mario Party (not sure if you're familiar with it), anyway one part of the game you had to shake the controller as hard and fast as you could and your little character was shaking pop - whoever's pop sprayed the highest one.
So one day we had an 'unbirthday party' (I'll have to explain that to you later...) for my boyfriend and we decided to try the pop contest for REAL. So we all went outside and shook up cans of pop as fast as we could. Mom said go and we all opened them. They actually didn't go very high, but it was fun. Also, we then proceeded to dump them on each other and had to hose off...:D
