Breaking Board Paradox
Publication No. 12923
Can a single sheet of paper hold a board that is struck with a hammer on the edge of a table? Demonstrate the tremendous force of air pressure.
Paper (20" x 30")
Soft pine board (1½" x ¼" x 24")
Wear protective goggles for this demonstration and have students (also wearing goggles) stand clear of the table during the demonstration. Students may want to strike a board without the paper on top. This is very dangerous and the fate of the flying stick very unpredictable.
