We're filming some chemistry demos for use in high school chemistry classes. I brought along my new Sigma 120-300 so I could stand back out of the way and grab some stills. This is what happens when you ignite a very small, hydrogen-filled balloon. I'll update this with other images from the other demos as we go along.
