An experienced chemistry professor used to say that it took about one explosion per week to maintain college students' attention in chemistry lectures. At that rate, we'd get in pretty big trouble with a lot of parents and teachers! Don't worry, we still have lots of bubbles, fizzes, bangs, and color changes for you to explore. … Read more
