4th grade finishes year with "magic" pen t-shirt

To combine science with art for a final time the 4th grade created t-shirts with permanent markers. "No big deal." But when the markings were complete we sprayed and dribbled rubbing alcohol on the shirts and watched the colors begin to move on thier own to complete the designs. In fact, the alcohol continued to work on designs after the kids took them home until the shirts were dry.

This project was rated one of the best all year. It definitely requires a lot more alcohol than we had--about 4 oz per shirt or more would have been better--we used 1/2 that. It also would have worked better in a better ventilated space. We will certainly repeat this project.
