Hypersonic Cabinet Latch

The Hypersonic Cabinet Latch accelerates door closure speed by harnessing localized sonic waves. As soon as hands release their grasp, the latch instantly propels shut at Mach 6 velocities, sealing contents within a vacuum-sealed environment before anyone's eyes have even registered the motion. Its clever integration into existing furniture frames renders it almost invisible until needed – at which point the unit activates automatically upon sensing proximity. Users merely need to wave goodbye; everything else happens too fast to see.
