Brushing Up With His Invention
DON LEVERIDGE, 22-year-old senior of the University of Chicago, demonstrates his revolving toothbrush, which uses a hand-operated crank as its power source. The young lady is using an ordinary toothbrush which, according to Don, is old-fashioned in the light of his invention. He has already talked 200 of his fellow students into using his type of brush, and has great hopes for marketing it nationally.
Hey Einstein! it takes double the effort to use your silly toothbrush!

A year or so later they came out with the steam-powered version and he was out of business.
