I was recently playing around in the lab and discovered a new experiment that is very easy to carry out, but also results in a variety of mysterious color changes. You can watch it in the video below.
Can you describe what is going on in this experiment using your knowledge of chemistry? Let me know your thoughts in the comments! I'll share the solution to this Chemical Mystery in a few days.
