Junglism, welcome to the forum, but you don't need to disintegrate the tube for a good effect. The 'boom' from well made BP is often much more satisfying than the 'crack' of flash.Another question I have is would it be possible to make black powder that disintegrates its cardboard tube like flash does? Would it have a similar report? Any advice on recommended chemicals to use for BP salutes like this?
As a bit of silliness (and mods please delete if inappropriate), I was interested to try a theatrical 'suspended airburst' effect safely over the holiday - 5g of riced BP with 2g dragons egg granules (<1mm) in a 3/4" x 2.5" tube with thin card end caps, hung clear of all hazards. Here's the vid:
Purple Dragon burst
The video doesn't capture the 'thud' of the burst, but the audience reaction gives a hint Oh, and the tube itself survived intact.... No need for flash here, so friends... work on your BP...
