Acoustic levitation is a technique where multiple speakers are positioned to create standing waves that can levitate small objects using sound. It’s even possible to manipulate the levitating objects in three-dimensions with the right set-up, but until now, the technology has been confined to the laboratory. Now a group from the University of Bristol has created kits and instructions allowing the curious to build their own acoustic levitators at home. In the video, Dianna shares some of her own adventures in building and playing with these DIY levitators and travels to the U.K. to see more from the creators.
