Milo: I drink the water and it goes into my belly, and then where does it go next?

Me: It gets sent to different parts of your body, and then you pee it out.

Milo: [stunned silence]

Me: Really.

Milo: You PEE IT OUT?

Me: Yes.

Milo: I want to go pee right now and see the water come out.

Me: Well it's just going to look like pee. It won't look like water.

Milo: You drink the water and then you pee it out.

Me: Yes.

Milo: And you pee out snack too.
