World’s Thinnest Screen Made from a Soap Bubble (video) reports that it’s fascinating to know what technology and its creators are capable of developing. The latest innovation in screen design comes from Tokyo, where University of Tokyo researchers Yoichi Ochiai, Alexis Oyama and Keisuke Toyoshima have developed what is arguably the world’s thinnest screen, made simply from a soap bubble.

Projecting an image onto soap isn’t as easy as it may sound. Typically light passes through a soap bubble in its unaltered form. To work around this problem, the researchers subjected the bubble’s membrane to ultrasonic sound waves, played through speakers. Sonic waves break up the surface tension, creating a texture to the bubble that becomes opaque, while reflecting enough light to project a vivid image for viewers.
