I am planning on making crackling fountains. I have made fountains containing aluminum, iron, mg/al etc., all of which came out well. I now want to make crackling fountains. I watched a video by Ned Gorsky in which he showed crackling fountains made by him but there was no mention of the composition, whether it was choked or open ended. I also tried searching this forum and other sites like Cannon Fuse, etc., but could not find anything on crackling fountains. I once tried to put some crackling stars in a regular fountain containing a slow composition, I added some alcohol to the mixture and pressed it in the usual manner with my arbor press, the stars just flew out without crackling. All information regarding crackling fountains will be highly appreciated.
