Gum bichromate
Gum bichromate is a really cool way to make pictures using colors and light. It's like magic!
First, you need a special paper called watercolor paper. Then, you mix some things together like gum arabic, watercolors, and bichromate. Bichromate is a chemical that helps the colors stick to the paper.
Next, you put the mix on the paper and let it dry. When it's dry, you take something called a negative (which is like a piece of clear paper with a picture on it, but it looks like the opposite of the picture).
Then you put the negative on top of the paper and shine a bright light on it. The light helps make the picture on the negative appear on the paper.
Finally, you rinse the paper with water, and the colors magically stay on the paper where the light hit it. And voila! You have a beautiful picture made with gum bichromate.
But remember to always be super careful when mixing and using chemicals!
