Liquid explosives are one of the biggest threats to airlines, but new liquid-scanning technology may help change that.

Some airports in the U.K. are testing new technology that would eventually allow airports to easy restrictions on liquids.

The machines scan containers in less than 10 seconds, uses radio frequency, uses ultrasonic technology, and alerts agents of suspicious substances.

The Ohio-based company which built the machines says the margin of error is "very low."

Right now, airlines only allow you to carry on liquids in a 3.4 ounce container.

The TSA says it will still be a long time before the U.S. eases restrictions on liquids.
