Vintage Newton’s Cradle “Swinging Wonder” by Scientific Demonstrators Inc.

Circa 1960s “Swinging Wonder” Newtonian demonstration tool. This interpretation of Newton’s Cradle was manufactured by Scientific Demonstrators Inc. of Eugene Oregon. Functions by manually initiating momentum with one of the five nickel plated steel balls suspended in the walnut frame. It illustrates Newton’s third law of motion (for every action, there is an equal and opposite reaction). Wonderful home or office conversational piece that is stylishly modern while remaining scientifically instructional.
Very, good, vintage condition with only minor wear to the walnut finish and nickel plate.
