New scanner to detect liquids tested

Homeland security officials are showing off the latest in future airport security technology — a machine developed at Los Alamos National Laboratory that can detect whether a passenger is carrying liquid explosives.

The device, about the size of a small refrigerator, measures the
chemical fingerprint of liquids — even those in metal containers.The device uses magnetic resonance to read the
molecular makeup of the liquid to determine if its something dangerous.
It can even tell the difference between red and white wine and different
types of soda.

Officials say the technology is still a few years away from being deployed to airports around the country.
