Anything Red . . .
And you think your garden tractor is hard to start.....
That "thing" is a piece of heavy paper that has been soaked in saltpeter. They roll it up and then light it to get an ember on it. The shotgun shells they use to do that are not as potent as a regular shotgun cartridge is. They have less powder and are setup to have a slower burn than a regular shell. Also they don't have bb's in them which I assume is obvious. They can be started on a regular handcrank as well and from what I hear that is the way to do it as the shells are hard on the bearings and the crankshaft.I'm still wondering about that thing he lit and stuck in it.
