This is probably the coolest art science project I've ever done. Anyone can do it and kids would have so much fun! I did this on watercolor paper, and I got the cyanotype solution on Amazon. It's linked on my Amazon page at https://www.amazon.com/shop/influencer-99922a4c?ref_=cm_sw_r_apin_aipsfshop_HKACH101Y2AGJB5Q6PMA&language=en_USi The full instructions were on the package, but basically you add water to the bottles, mix equal parts of the solutions in a container and coat the paper. Let the paper dry and then keep it out of the sun until you're ready to expose it with whatever you want the image of on top. Lay it in the sun for about 30 minutes and then rinse with water or water and peroxide if you want faster developing. It is magic!
