Shiny Happy People Pooping Beads

Middle C likes to put things in her mouth. She is four, but still has some sort of oral fixation going on, my fault I'm sure. I am constantly telling her to not put things in her mouth. The other day we watched the Magic School Bus meets Digestion. It was all about what happens when you eat. Middle C, glances over at me and asks,"So what if I swallow a quarter?" I told her that it could hurt her delicate insides since it was so big, and she would have to go to the Doctor. After discussing the quarter, she continued to assault me with question after question of objects that she could potentially swallow. The following day she slinks into my bedroom and tells me that she is a scientist and she is "having a secret experiment". I kiss her on the forehead and mummer, "that is awesome that you want to be a scientist." I suppose that I should have probed for more information... That evening she excitedly waddles into the living room, with her princess panties around her ankles. "Check out my poop mommy, my experiment worked, I pooped out a bead, and it is still a shiny, sparkly, green. It did not even hurt, I am a real scientist now!"
