To test future rocket designs, NASA is employing an age-old bar trick: Slowly and deliberately apply pressure to an aluminum can until it crumples. No foreheads will be involved, however.
In late March, engineers will use a million pounds of force to crush a 27.5-foot diameter, 20-foot-tall canister made of aluminum and lithium, hoping to learn more about shell buckling so they can design sturdier rocket skins.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
