According to Moscow News, Oleg Gadomsky, a professor at Ulyanovsk State University in western Russia, has patented a method of making objects invisible - an "invisibility cloak."
Apparently he has invented a sub-micron stratum of microscopical colloid golden particles that makes an object placed behind it invisible to an observer. He believes it will soon be possible to have a Harry Potter cloak.
I used to have something like that when I was 15. It made me invisible to girls!
