Chemical engineer

The chemical engineer is a chemical engineer who presented a booth on "Chemistry: The Science of Goo (and Glop)" at the STEM Conference.

History
When Bart was bored at the STEM Conference, the chemical engineer approached Bart and told Bart that he was going to show Bart something interesting. He told Bart that he used to be like him, not interested in science. Bart wasn't interested until he saw the chemical engineer cause a small explosion. Bart then told him that he liked him, except his lab coat made him look kind of heavy. The chemical engineer then replied that he was kind of heavy and the lab coat made him look thinner.
