(Phys.org) —A team of researchers with members from the U.K., Scotland and the U.S. has built a functioning acoustic tractor beam in a lab—one that is able to pull objects of centimeter size. In their paper published in the journal Physical Review Letters, the team describes how they built their device, why it works and to what applications it might be put.
