[article] Are you tired of having airport security screeners toss away your bottles of water, shampoo or lotion? Change is on the way in some parts of the world. Battelle, a nonprofit research and development organization in Ohio, has built a screening device that London's Heathrow Airport began installing last week to test liquids carried by passengers onto planes. Heathrow Airport screeners will begin using the device in January, when the European Union will start allowing some liquids, aerosols and gels onto planes under a phased timetable. In the U.S., Transportation Security Administration officials are looking into several technologies for liquids screening. Battelle officials say their liquids scanner, the LS10, is among those devices. But the TSA says you shouldn't expect to carry your favorite bottle of soda or shampoo onboard at U.S. airports in the near future. "Liquid explosives are a serious threat, and we aren't ready to move away from the ban on liquids," the TSA said in a statement.
