1" in diameter sanded smooth wooden sphere

How did physicists conduct their experiments needing a steel sphere in the old days? They used wooden ones of course. Sanded smooth and 1" in diameter this wooden sphere can be combined with other spheres of various composition (steel etc.) to show how the rolling stopping distance varies with each material due to the difference in the coefficient of friction for that material. They also make a great relic for the grandkids when describing what physics "used to be like".
