Fireworks are popping around my little town of Woodstock, Maine this evening. To my dogs the sounds of fireworks are the sounds of the sky falling. The upside of hearing the amateur fireworks displays is that it reminded me of a couple of videos about the science of fireworks.

If you or your children are wondering how the fireworks actually work, take a look at the following videos from National Geographic and Discovery News.

Both of these videos could be the basis of a flipped science lesson. In this post I provided an overview of how to use five services to create flipped video lessons.
