Nah. you don’t need no funky pills to see this. Now you can rule the kingdom with this trick with a book. This ‘Rainbow In Your Hand’ flipbook was created by Masashi Kawamura and it is still as wonderfully useless and pretty as it was back in 2007 in Japan.

This ‘Rainbow In Your Hand’ flipbook is a 13×6cm of 36 black pages. Seven squares with seven rainbow colours are printed on each page, next to each other. Just flip the book and the afterimage of the coloured row will appear. Best show off this trick in a black tee though. Uhm yeah, that’s all.

Check out this demo.

Get yours here. And no, you won’t be able to see any pink zebras… If you do, please consult a doctor.
