Very impressive.


There are very few problems that cant be solved with explosives.

                             Explosives are a bang up job.

Hello togehter, thx for the feedbacks!

 

Here is the star composition, calculated on 100g complete comp:

 

Potassium Nitrate: 36g

Sulfur: 9g

Charcoal (Pine): 29g

Mixed Charcoal (50%Pine, 50% Vineyard) 80 Mesh: 14g

Titanium, Sponge, 40-80 Mesh: 7g

Dextrin: 5g

 

Manufacturing process:

 

KNO3 + Pine Charcoal + Sulfur + Dextrin inside a ball mill, milling time 2 hours, add Titanium & mixed charcoal by screening.

 

For star pumping, the comp has to be dampen with plain water.

Nice breaks! What's the reinforcement material you're using on the shells? Doesn't look like gummed tape.

Stefan, very impressive. Einfach Geil!

 

The global "rythm" of the display is nice to watch, starting with hard breaking shells, fast stars, and going to slower long lasting stars, curved trajectories, with I love that.

 

- Do you mind to share a little info about the 4-comets shots at the beginning (at 1:42)-  some Titanium I guess - but maybe a few hints to produce such a nice composition?

- I do love the effect at 11:00 (or 10:59 as kaotch wrote!)
