Scientists at Princeton University have successfully developed a thin plastic sheet that can swim through the air the way skates and rays swim through the ocean.
The 10cm sheet of smart transparency is driven by ripple power, waves of electrical current driving thin pockets of air from front to rear underneath.
The prototype moves at speeds of about a centimeter per second. Improvements to the design could raise that to as much as a meter per second.
With the current status of the project, it would take a carpet at least 50-meters wide to support a human.
