Food in the tummy...

So recently, we asked Daniel, "Hey Daniel... do you know where the food you eat goes?"

He didn't know. (Note the uncertain look on his face, above.)
So we told him:
"It goes inside your tummy!"
He was kind of amused by the idea. He wanted to check for himself. First by touching it (above), and then by looking for it (below).

"So, where is the food?"

He wasn't sure why he couldn't see it or feel it. He still might not believe us...
