Description:
Breaking Board Paradox
Specification:
Breaking Board Paradox -Don't know your own strength? It's entirely possible. Lay our thin slab
of wood on a smooth surface with newsprint over half of it. When you
strike the slab, what happens? Due to its large surface area, the
inertia of the air is sufficient to hold the board in place. The board
breaks rather than sliding away. Includes enough wood for 10
experiments; instructions. You need newsprint.
