I originally saw this trick used in making tie dyed t-shirts with Sharpies and rubbing alcohol. I'm not really into tie dye shirts so I tried it out on a different medium, glass; specifically, I wanted to use this technique to paint a glass ornament for Christmas. In this instructable I will show you how I did just that.

While making my ornament it occurred to me that this project demonstrates some simple principles of solution chemistry so I included a learning objective and a discussion of the science behind it so I can enter it into the Teacher Contest
