Bullets don’t just bounce off Superman, they don’t even slow him down. Real-life police and soldiers can’t say the same, even when they’re wearing a bulletproof jacket of Kevlar or something similar. Although bullets don’t penetrate–the bulletproof material spreads their force–the force is still tranmsitted to the tissue underneath the bulletproof shell, causing severe bruising or even organ damage.
Now engineers from the Centre for Advanced Materials Technology at the University of Sydney have found a way to use carbon nanotubes to not only stop bullets penetrating material but actually rebound their force, so bullets can be repelled with "minimum or no damage to the wearer of a bullet proof vest.†(Via Science Blog.)
If they can just nail the X-ray vision, super-strength and flying stuff, they can break out the red-and-blue tights.
