At last, you can make things disappear. Scientists have created a device for disappearing unwanted objects. The crazy part is that it can make objects seem to appear as well.
Physicist Che Ting Chan, of the Hong Kong University of Science and Technology, told New Scientist:
Invisibility is just an illusion of free space, of air. We are extending that concept. We can make it look like not just air but anything we want.
With his equations, he can make visibility an illusion as well.
The device — which exists only as a design so far — would use existing metamaterial technology . It would create a series of filters that first render one object invisible and then another one visible. Continues New Scientist:
