Did I get this right? The guy put a bomb out there (the white thing), probably with some food on it, then shot the bomb? Why else the rifle?
Ammonia nitrate mixed with aluminum powder. You can buy it in kits to mix before shooting, or you can buy the two ingredients in bulk. Get the Ammonia nitrate from the local farm supply, and the aluminum powder online.
At least thats what I hear ;)
