Combine some iron oxide (rust) with a little aluminum and you get some really nice sparks as well as some microscale chemistry.

Carl, I have videoconferenced with you and with my 8th grade classes from New Jersey a few years ago. I need to access the slow motion videos you shared with us and to download them again. They were terrific but I don’t have them anymore!! Please send me a way to access them again! I find that the students of this age are able to understand Newton’s laws much more easily when they have videos that let them see inertia in slow motion. They cannot believe the water in the balloon holds its shape when the balloon unwraps around it! Thank you, Carl!!
