Travel back to a time when kids played with radioactive science kits, looping death trap waterslides, lawn darts, and toy guns powered by real explosions. This episode uncovers the insane rides and toys that turned childhood into a dangerous but unforgettable adventure. Hazardous History with Henry Winkler tells the nostalgic "back in my day" tales of unregulated experiences from a time before we knew better. Each episode tells the stories of the things Americans did for fun, for money, or out of plain boredom that you can’t do anymore. Pastimes, practices, and products that were once allowed, even encouraged, which you will never see again in modern America.
