Just when we’ve finally figured out how to comply with those complicated liquid and gel restrictions at airport security, they could be on the way out — at least in Europe.

Last week, London’s Heathrow Airport began installing screening devices that can test liquids, gels and aerosols in a variety of containers, reports the Los Angeles Times. The devices, made by the Ohio-based Battelle company, use radio waves and ultrasonic technology to scan for explosives. To see the machine in action, check out the following video from Battelle:


The Los Angeles Times reports that Heathrow will begin using the technology in January, but only for medicine and duty-free liquids. Assuming the initial results are good, the airport may start to permit other liquids and gels through the new screeners within the next year. The European Union is hoping to lift the liquid and gel ban in all of its airports by 2016.

Here in the U.S., Battelle’s liquid scanner is one of several types of technology being considered for use in airports, but the Los Angeles Times quotes a Transportation Security Administration (TSA) statement that doesn’t seem to bode well for any quick changes: “Liquid explosives are a serious threat, and we aren’t ready to move away from the ban on liquids.”

Bottom line: Don’t leave your quart-size bag at home just yet.
