Ella and Herbie, twins, have moved to a new house. While their mom goes shopping for hardware supplies, the local handyman Mr. Mital keeps the children busy by having them help him with his work. Along the way, he points out a variety of inventions that were created by African-Americans. Flaps fold out from the pages with more information on each adventure. I enjoyed the combination of a fictional story with facts about inventors, and it’s sure to make you want to learn more about who invented the things around your house.
