To protect against more energetic abuse, say an enthusiastic whack from a karate blackbelt, superflexible, springy "bubbloy" absorbs the energy of the impact by crumpling up. After the impact, the bubbloy pops right back into its original shape. The alloy--a mixture of palladium, nickel, copper and phosphorus that's fairly lightweight and can be squished like a red rubber ball--was developed at Caltech.Illustrations by Kenn Brown and Chris Wren
