1F20.22 Hit the Nail on the Head

The instructor places a double thickness 2 x6, with a nail sticking out, on a stack (3 or so) of physics books, on their head.
Either the instructor or a student pounds the nail into the wood.

You have to trust the person with the hammer. Watch the fingers <:-0

 

Two 2 by 4 segments of pine wood, probably around 6 inches long, are stacked on top of each other. A nail sticks out of the top segment. A stack of four thick introductory physics textbooks rises behind the blocks. A hammer sits in the foreground.
