Viewers may soon be able to watch films on soap bubbles - after researchers developed a technology to project images on a screen made of soap film.
An international team produced a display that uses ultrasonic sound waves to alter film’s properties and create either a flat or a 3D image.
The bubble mixture is more complex than the one sold in stores for children, but soap is still the main ingredient.
The team says the display is the world’s thinnest transparent screen.
"It is common knowledge that the surface of soap bubble is a micro membrane. It allows light to pass through and displays the colour on its structure," the lead researcher, Yoichi Ochiai from the University of Tokyo, wrote in his blog.
"We developed an ultra-thin and flexible BRDF [bidirectional reflectance distribution function, a four-dimensional function defining how light is reflected at an opaque surface] screen using the mixture of two colloidal liquids."
Although traditional screens are opaque, the display created by Dr Ochiai and his colleagues Keisuke Toyoshima from the University of Tsukuba in Japan and Alexis Oyama from the Carnegie Mellon University in the US, varies in transparency and reflectance.
The team managed to control and exploit these properties by hitting the bubble’s membrane with ultrasonic sound waves, played through speakers.
Sonic waves alter the texture of a projected image, making it look smooth or rough.

Government agents ’directly involved’ in most high-profile US terror plots 2014 07 21
Nearly all of the highest-profile domestic terrorism plots in the United States since 9/11 featured the "direct involvement" of government agents or informants, a new report says.
Some of the controversial "sting" operations "were proposed or led by informants", bordering on entrapment by law enforcement. Yet the courtroom obstacles to proving entrapment are significant, one of the reasons the stings persist.
MH17: Are Pristine and Expired Passports a Smoking Gun for a False Flag? 2014 07 21
As the dust settles on this latest air tragedy, a number of very visible anomalies exist, all of which have been willingly glossed over by western media analyists and government officials.
Putting the current media storm into context, it’s essential to establish the political motives of those parties rushing to assign blame. Western government and major western media outlets, namely ...
