MAC’S MARBLING began when Bob MacDonald retired as a university professor and research scientist with expertise in surface tension. In retirement, he began using that knowledge to create intriguing swirls of color through the process known as marbling.

This fascinating pastime of marbling led to an opportunity to raise money for another of Bob’s interests: STEM education of K-12 students. More than ever, kids need to find out how important science is in our daily lives and how much fun science can be.

We’d like to encourage you to support MAC’S MARBLING by heading over to your local East Bay coffee, art, or knick-knack shop to see if they offer one of our bright, colorful MAC’S MARBLING products. If they don’t carry our products, feel free to contact us and the owner of your store to see how they would feel about offering our pieces. Remember, all profits from the sale will support science teaching in local K-12 schools!
