Thank God it worked, I guess.

Bulletproof glass wasn’t officially patented until 1982, but that doesn’t mean it didn’t exist. The idea of laminating glass traces back to the early 1900s, with a chemist named Edouard Benedictus debuting the idea of “safety glass” after witnessing a plastic-coated beaker crack instead of shatter.

This, of course, inspired him and others to develop the idea into something that could stop a projectile, like a bullet. And what better way to show that off than having your wife hold the glass while you shoot at it?
