RE: ballistic jelly
There is no way to make your own that I Know of. Their is a company (Kind & Knox) that makes it. It is very expensive though. A 25# drum costs $275 plus shipping and handling. At least thats what it cost last time I bought a drum. And that was in spring of 2000. Here is the company info if you are interested. Hope this helps.
