Now that August is here, school is just around the corner. Therefore, I thought I'd share a new chemical mystery to get us all back in the spirit of teaching and learning. Can you use chemical principles to describe what happens in the experiment seen in the video below?
Let me know in the comments if you have any ideas for how this experiment works. I'll share the solution in a few days.
