The popping Coca cola

We had dinner at a fancy restaurant. My daughter had ordered Coca Cola. I was just drinking water but I was also given Coca cola. As my stomach does not like Coca cola but my brain does...my stomach wins...so when my daughter had finished hers she took my glass. She but the glas in her mouth and we heard a popping sound. She looked surprised and afraid. The glas it self cracked. Fortunately she didn't get hurt. But of course it had to be my glas....this has never happened before....how weird!
