I am always trying to find a safe inexpensive ways to improve my fireworks. Last 4 th. of July I came up with nice replacement for fire cracker tubes which can also be used as reports in a mortar shell. I had ran out of tubes and forgot to order more in time for the 4th. I decided to run to Menards to get some hdpe pipe to make mortar tubes. As I was walking in the pipe section I noticed a shelf with 5 foot 1/4 inch terra cotta pex tubing for $1.59 a piece. I cut the whole thing in 2 inch pieces about 30 in all. I tried filling them with black power and they just didn't have much pop so I decided to use a 70/30 mix of KCLO4 and dark aluminum. I sealed the bottoms of all of them with hot glue put the mix in the other end followed by twisting a fuse half way into the mix. I sealed the fuse end with epoxy but you could probably use a glue gun if it is unplugged. I was really surprised at the bang when I lit off the first cracker. For something no bigger than a black cat it sure had a loud report. Another thing that amazed me was that the case stay almost always in one piece blowing out one side and can be easily picked up and thrown away. Whereas PVC and other types of pipe shatters to tiny pieces these don't. If anyone wants to try this let me know what you think . And if you have any questions just ask and I will get back as soon as possible. Thanks Have a great day and above all Be Safe!
