Newtons Second Law of Motion

Which ball will strike the ground first, one dropped to the floor or one shot outward?

Since this is contrary to what you may expect, your class will have to "see it to believe it". Includes aluminum base, spring plunger with 2 settings, 2 steel balls (1" diameter), instructions with theory and experiments. Weight 8 oz.
