It works, lemme show you
If you’re going to introduce an insane product to the market, you’re going to have a difficult time finding people who’ll test it out. Or, if you’re the inventor of the bulletproof vest, you’ll have to grow some big ones and do it yourself.
To prove that his bulletproof vest was actually bulletproof, Casimir Zeglen decided to put one on and have a volunteer shoot him in the best. Thankfully, nothing went awry that day, and he would live to produce these vests for police and military forces. If nobody believes in your product, you gotta be willing to show them how it works.
