No. Reality ! These great-looking hard rubber balls were used in a paper mill. They
rolled around inside a drum mashing the necessary ingredients into pulp.
The wonky, less round looking one (above) was attached by the remnant of heavy
fabric to the inside of the drum to keep things stirring. The perfectly round ones in
the cart (below) were loose and did the real mixing work.
Lucky me to know pickers with eyes so good that they see the beauty in old stuff
that others would send to the dump.
Are the balls from the paper mill for sale? I teach physics and chemistry in a paper mill town. Would make an interesting item for class. Bob J.
