My sister's friend was told when she was 13 that if you have Pop Rocks candy in your mouth and take a sip of soda, you will explode. Being the bright child she was, she immediately tried it. It nearly worked. The soda made the candy flare up in her mouth, causing her to spew it all of the sink. It was one of the funniest things I ever saw.
