The screen you can see through
Scientists in the US say they have made a transparent screen that can be "stuck on" to any window, turning it into a screen that moving images can be projected onto.
The screens are made simply by adding tiny nanoparticles that reflect blue light into a liquid polymer.
When that liquid plastic is set into a screen, it remains transparent, but any images projected onto the screen in blue light are reflected and revealed by the tiny particles.
The breakthrough, demonstrated here, is published in the journal Nature Communications.
