I am going to be filming an action film soon and I need to some explosives to use in some shots. Anybody know how to make some? I can get pottasum and all that stuff I just don't know how to make it. I also need an electric fuse so it can be set off manually not by having to wait. So if any one knows how to make that too. I was going to use black powder but wondered if there is a better way. It will be covered with dirt to make a dirt explosion not all fiery.
