Ace in the Face

Upon waking, actually before fully waking up, Adriana rolled over and said "mom, I remember being in your tummy. It was black and hazy and we were yellow"
Me: could you see your sister?
A: yes, she was yellow too.
R: (popping out of the blanket) I remember too, I was in this position (balls legs up to chest) and I was playing cards. (With a goofy face)'ya got an ace'"
Later, when getting dressed...
R; Adriana, I can see your butt!
Me: could you see each others butt in my tummy?
A: yes. Then I sat on her and dropped an ace in her face.

She bothered me with science.

Ruby (5) to Harper (2) (while eating raisins): Harper, if you eat this, it will travel down your body, you will poop it out, it will travel to the sewer, rats will eat it, they will poop it out, then it will live on for eternity getting eaten and pooped out. It is like it will be forever on a water slide or at a water park. 
Me: why water slide and water park?
Ruby: Because your body is like a water slide for food, then when it comes out, it lands in a water park where it waits for the next water slide. 
Harper: I don't want to talk about it. (throws raisin on floor).
