Happy Independence Day to all of my fellow Americans. Probably many of you will be enjoying fireworks displays this evening. If you or or children are wondering how the fireworks actually work, National Geographic has a short video for you. In I Didn't Know That - Fireworks we learn how fireworks get their shapes and colors. The video is embedded below.
Don't try this at home.
Happy 4th of July!
