Chemical Mystery #18: Peek A Boo Blue!

Blue Powerade turning green, and then yellow.

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?
