With US Independence Day this week, I thought a couple of science-y videos about fireworks might be appropriate. I can’t embed the first video from WIRED, so you can watch it here. It’s a short animation of the science — and particularly the chemistry — of fireworks. The second video, from the German children’s program Die Sendung mit der Maus and embedded below, shows fireworks being hand-packed to make a smiley face in the sky. That video is only in German, but the show is quite good on science and engineering topics and this clip is no exception.
Wednesday film(s): Fireworks!
