Herring fish communicate by farting. When herring fish release gas, the bubbles they produce make a high-frequency sound that only herring can hear. The fish use this noise to arrange themselves into “protective shoals” during the night to keep them safe from predators.
100 Mind-Blowing Protective Facts
Bubble wrap was originally designed to be used as wallpaper. Bubble wrap was born in 1957 when engineer Al Fielding and Swiss inventor Marc Chavannes tried creating a textured wallpaper. However, their product was rejected. They also tried marketing it as a greenhouse insulator, but the material still fell short. However, when IBM released a new computer, Fielding and Chavannes pitched their concept as a protective covering for computer shipments. From then on, bubble wrap was adopted as the go-to protective wrap. The third time’s the charm, I guess.
Sunglasses were not originally designed to protect your eyes from the sun. The original idea behind this was so that Chinese judges could hide their facial expressions in court. Today, they mainly serve as protective eyewear and as well as fashionable accessories.
