This tutorial will teach you how to make a salute from scratch.
Disclaimer: even though firecrackers are fun, they are still explosive devices and can every dangerous if misused,also
this process involves making an explosive powder, so wear safety goggles and NEVER mix the chemicals in large quantities.
With that said, enjoy this tutorial and have fun !
This powder composition is very friction sensitive and should only be mixed by pouring back and forth between two sheets of paper.
(parts by weight)
potassium nitrate : 5
pyro aluminum 400 mesh : 2
sulfur : 3
never mix in quantities larger than a tablespoon ! (you only need to fill each salute 1/3 full any way.)
Ok, pretty much all you need to do to make the casings is wrap thin cardboard around a dowel until a tube with a reasonably thick wall is created and glue the end of the strip used to make a casing so it doesn't unravel. then cut out two disks the size as the diameter of the tube out of the same cardboard and using the dowel force the disks through the tubes to form end caps. now simply glue one endcap into place tightly and poke a hole in the middle of the tube for the fuse.
Now all you have to do is glue in a fuse (home-made or bought) fill the casing with composition 1/3-1/2 full and glue in the second endcap.
ps: the end cap should not compress the powder, if it does remove the excess and continue.
All you have to do is have fun and keep safe !
