This special blue paper is UV sensitive! Place whatever objects on it and expose it to sunlight, and watch it change color before your eyes! Run the paper under water to capture the shadow of those objects. It's like very first simple photo developing with no weird chemicals and a very magical result. This process is called cyanotype! That's a fact, Jack.
This contains just the magic paper, and that's really all you need! You can also use this as a refill for our Solar Print Kit.
