I have a story to tell it about the fifth picture
I saw a model of a tap of water in a library
it was not attached to a wall, it just was stopping on the table and it was pouring water
I felt like to know where the water was coming!!?
So I wanted to touch it while a librarian didn't see me
but he turned around to me and laughed at me
He excepted I will touch it
I was so embarrassed
By the way, I tried all of them
