The Orange Goo Used In Everything From Armor To Football Helmets

dryriver writes:CNN has a story about a slimy, gooey orange gel developed by British company D3O as far back as 1999 that is very soft and fluid-like normally, but that hardens immediately when it receives an impact: It's a gel that acts as both a liquid and a solid. When handled slowly the goo is soft and flexible but the moment it receives an impact, it hardens. It's all thanks to the gel's shock-absorbing properties... Felicity Boyce, a material developer at D3O, told CNN, "if you hit it with great force, it behaves more like a solid that's absorbing the shock and none of that impact goes through my hand." American football has become a huge market for the British company, where the gel is incorporated in padding and helmets to absorb the impact of any hits a player receives. D3O claims it can reduce blunt impact by 53% compared to materials like foam. The material can also be put inside running shoes to improve performance and reduce the risk of foot injury. Usain Bolt ran with D3O gel insoles in his shoes at the 2016 Rio Olympics. The material is being tested in body armor. "While we don't have a material that can stop a bullet, we do have a material that can reduce the amount of trauma that your body would experience if you got shot." There are also soft smartphone casings using the gel that harden when the phone is dropped and hits a hard surface.
