Tupperware Cup Story

My wife called me at work the yesterday to share a funny little story. She normally takes a large Tupperware cup of water to work with her. Yesterday she had finished her water and refilled it with 7up for a change. As she was walking down the hall at the place she works with her beverage in her hand, a large bang was heard. She looked down and realized that the cover to her cup had flown off. Apparently her walking shook-up the 7up creating pressure on the lid till it burst off. It startled her pretty good since she carries her water around routinely without any such events taking place. A guy standing next to her said, “Jeez, I thought a bomb just went off.” Fortunately the only damage was some spilt 7up and everyone got a good laugh out of it.
