Cats got one step closer to world domination last week when scientists in Singapore and China premiered a box that could effectively make anything placed inside it invisible. The magical box is just one of three new “Harry Potter”-style invisibility cloaks announced this month, which follow numerous such announcements
made so far this year.
The invisibility box comes our way via Dr. Zhang Baile, a researcher with the NTU School of Physical and Mathematical Science. His team’s small device — the details of which were published in the journal Nature Communications
— is called a “ray-optics cloaking device.” It’s a small, glass-like box made of more than two dozen internal and external angles that effectively bends light around anything in its center. When light is shone at the semi-transparent box, it passes around the box instead of through it, effectively masking whatever is inside. Zhang and his fellow researchers tested his device with live cats and fish, as you can see in this image from the paper:
