Steve Spangler Science: Goldenrod Paper Message

Use this special pH indicator paper for some spooky Halloween science.

The term goldenrod is typically used to describe a color of paper – golden yellow. 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 share 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.
