Copper Thermite Line

This is a video showing a line of copper thermite burning. The fuse hung up twice and I was getting ready to put another fuse in when the stuff burned.

Surprisingly I wasn't burned by the thermite, but by the piece of fuse in my hand. I reflexively held onto it and the thermite ignited the fuse. It's really minor, a little first degree mark on two fingers. My fingers are beat-up from all the stupid stuff I do anyway.
