This open-to-the-public museum, library & learning center features the history of chemistry.
"The Franklin Institute might be Philadelphia's best-known science museum, but the Science History Institute (formerly the Chemical Heritage Foundation) is an insider-favorite. The museum, which pays homage to the actual practice of science and its life-changing discoveries, is located right in the heart of Old City, on the ground floor of the Institute's contemporary glass building. Despite its small size, it completely delivers with a fascinating collection of items, all of which serve to elucidate the mysteries of everyday life—how crayons get their colors, or how plastics are made." - Nancy DePalma
