Forgotten picture...It makes me laugh!

So This picture is from the world of science (or science center)...I forgot I took it until I was looking for a picture to write about. It says How does a flush toilet work? Then it goes onto great detail to explain how exactly a flush toilet works...(yeah you probably could have guessed that from the title on the poster.) But I found this hilariously funny when I entered the stall in the bathroom. So I had to take a picture of it. It's funny because I found it in the bathroom stall on the wall...a little reading material I guess incase your trip to the bathroom takes awhile.
