The Day-Glo Brothers is the true story of Bob and Joe Switzer's discovery of florescent paints and their applications. Joe, a novice magician, wanted to spice up his magic act. Bob, unable to pursuit medicine due to a work injury, helped Joe experiment with ultraviolet lights. Soon they noticed that some chemicals left by their pharmacist father glowed under the light. Through trial and error they discovered florescent paint. When WWII arrived, the military found multiple uses for the paints, and eventually the brothers were wealthy. Now florescent paint is used everywhere and we have the Day-Glo brothers to thank for their discovery. This is a great book for kids who love finding out about the origins of products or are interested in scientific inventions.
