Make a rainbow over your hands
This book uses the same principle of a flip book to give us the visual sensation of a rainbow.
The way in which a real rainbow is formed is very different. In the sky the colors are formed by the decomposition of white light inside of little particles of water that make the clouds.
Here a strep with some colors of rainbow is placed in each page of the book, when we flip it the rainbow appears. A phenomena called visual persistence allows that, to see more about visual persistence click here.
