With soap as a core ingredient in its mixture, the membrane surface lets light pass through it and reflects a range of vibrant and vivid colors of projected images without a threat of getting burst like a regular soap bubble.
It uses the Ultrasonic sound waves to play the trick for you, making images look either smooth or rough. The duo from University of Tsukuba (Dr Ochiai and Keisuke Toyoshima) and Alexis Oyama from Carnegie Mellon University believe it is the thinnest transparent display that is known to a man as of this moment.
With the combination of membrane as thin as of this display and Ultrasound waves researchers controlled its surface and transparency level. By stacking several bubbles together a holographic projection can be achieve, on the top of 3D effect.
It can be an interesting investment for Museums and Magicians.
