This man can float with one hand touches wall; I repeat, is “touch,” not “hold!” We all know that this incredible stunt is just an illusion but do you know how he did it? Well, the answer is very close to my “assumption;” means what? I have that talent too…!

Hit the jump for more photos of his incredible performance at different places; the last photo revealed his secret.

Rainbow in Your Hand is a flip book that designed by Japanese art director and copywriter Masashi Kawamura. This 36-page book is not for your to read but to flip. Every page has an image of the color spectrum against a black background, it then creating the illusion of an arced rainbow hovering above the pages as the pages flip by.

This picture shows a lady is playing orchestra, which is an optical illusion image with title “Two Heads Better Than One.” By looking at its title, it should be another head “hidden” somewhere inside the picture. I like to challenge this type of optical illusion but I couldn’t find the answer for this one. I googled around and found some “answers” but none of them can convince me.

Hit the jump to see the “not so convincing answers” and please leave a comment if you managed to spot the hidden head.
