Henry Winkler on ‘Hazardous History’ Season 2: ‘We’ve Unleashed a Monster!’

Season 1 of Hazardous History With Henry Winkler revealed the dumb, dangerous and potentially deadly side of the good ol’ days.

Celluloid combs that burst into flames. Lawn darts that produced 23,000 pounds of force per square inch. Baseball promotions that devolved into riots. A toy pistol that used explosive acetylene gas. Health tonics that were infused with toxic radium. Electrified belts that delivered “soothing current” to the male genitals.
