Pop It!

I remember when Pop Rocks first came out in the 80's.  It was a hit.  Just imagine shards of sugar pieces with a secret surprise.  When they are hydrated with saliva, the pop rocks candy starts to crackle and pop.  It even has a sensation of popping in your mouth when you close it.  I heard some rumors however about a possible danger.  Drinking soda after consuming pop rocks  was said to pop your stomach.  Careful not to chance it being true, I stayed away from that.
