An inventor at Johns Hopkins University’s Applied Physics Laboratory has dropped his research in biomechanics and outer space to create non-lethal toothbrushes for prisoners. While others have devised wiggly toothbrushes, mini 3-inch toothbrushes, and fingertip toothbrushes held like thimbles, Paul Biermann is using molecular manipulation to create a toothbrush handle that can’t be reshaped.

Once he’s got that refined he’ll turn to toothpaste tube caps that automatically close when you’re finished brushing your teeth, toothbrushes with handles thin enough to fit in your toothbrush holders, and smart-designed best toilets in 2018 along with the toilet seats that automatically lower after a man flushes the toilet.
