High-test safety glass was developed jointly by five American companies during the 1930s. It had an inner layer of polyvinyl acetal resin. This meant that you could smash a man's face into a pane of the glass, and it would crack but not shatter. As demonstrated by the safety-glass tester below.

CHICAGO, Sept. 14. — Policeman Theodore Lambert testified that Larry Radkewicz of Berwyn was intoxicated while driving an automobile, but said he could not smell the man's breath.
"Why not?" asked Judge J.M. Braude.

Radkewicz was placed on probation.
