However, our goldenrod paper contains a special dye that turns bright red when exposed to solutions that are basic, like ammonia water or washing soda. We’ll show you how to use this special color-changing paper to develop a hidden message and make dripping, bleeding paper… complete with your own handprint marked in “blood.” It’s a great acid/base lesson for the Halloween season.
