dynomike1 Posted December 6, 2014 Posted December 6, 2014 Has anyone seen how they make a ground burst the one in this video @ is awesome. 1
Mumbles Posted December 6, 2014 Posted December 6, 2014 I suspect most people's answer will be not intentionally. If you look closely that is actually on a lake or body of water. You can find them occasionally called "frogs" I think. Basically it's half a shell with something floaty like styrofoam around it to orient it. Shells break bigger than you expect.
MrB Posted December 6, 2014 Posted December 6, 2014 Looking at the break & star formation i'd expect something more like a cone shape, then a half sphere, but that might be an artifact of sitting on the water? Anyway, it looks quite nice.B!
nater Posted December 6, 2014 Posted December 6, 2014 The only intentional ground burst I saw was made 1 shell hemi filled as normal and the other filled with kitty litter. This was lit in the winter in a large harvested field. The break was a dome or half sphere shape and large. Mumbles is quite right, most ground bursts are mishaps. Fireworks look different from the inside looking out.
Arthur Posted December 6, 2014 Posted December 6, 2014 Someone in the UK tried using commercial shells as ground shells, it's surprising how far they spread. Don't try one without a LOT of space, and a LONG firing cable, you really don't want to be inside that. IIRC a 3" shell stood on a 2" mortar (ie off the ground really) needs about 400m safety distance.
dynomike1 Posted December 6, 2014 Author Posted December 6, 2014 Now i know why i never saw anything on this.
fredjr Posted December 7, 2014 Posted December 7, 2014 One of my shells that were the final shot of the BPG show at PGI did something like that. BUT certainly wasn't intentional, lol...https://www.youtube.com/watch?v=UN4YCamPw6I&list=UUKBY4yFI_48VdA2uQBql4UQ
