The Science Behind One of Chemistry’s Most Fascinating Clock Reactions

@inventionshark on Instagram: "In 1959, automotive designers proposed a radical safety idea: a horizontally spinning wheel mounted to the front bumper. The rotating drum was meant to absorb low-speed impacts and roll against obstacles, reducing damage by redirecting force sideways instead of crumpling metal. The concept was never produced due to cost, complexity, and better emerging solutions, but it reflects a period when car safety innovation was highly experimental and unconstrained by conven
