4" C8 to White strobe stars

[redbullzuiper]

4" Ball shell

 

Stars are rolled, size of the stars are 10mm, strobe stars are 4mm, C8 6mm. No prime in between the two layers.

No prime needed as C8 composition is already so easy to light.

C8

Potassium nitrate ................ 49

Sulfur ................ 6

Charcoal ................ 40

SGRS ................ 5

 

White strobe (JOPETES Strobe formula)

Barium nitrate ................ 52

Potassium nitrate ................ 4

Sulfur ................ 26

Magnalium 63 micron, 250-mesh ................ 14 (original calls for 230 mesh, I didnt have. I bet using 230 will be better. I will use 100 mesh next time to see if that makes it even more strobing)

SGRS ................ 4

Could you see the C8 in reality, because on the video it is difficult or impossible to see.?

(Unfortunately, this is often the case with pure coal streamers).

But the strobes were very nice with a good hangtime. Good break as well.

It was a bit misty :/

 

I was directly under it and could see it much better than the spectators, who were around 200m away from me.

This is an older thread, but I've been playing around with the Jopetes strobe formula lately and I wouldn't recommend using 100 mesh, as it slows the strobe WAY down and makes it very difficult to ignite.  The larger the mesh size, the slower the strobe.  Even with various hot primes at least half of mine were blown blind.

I would also recommend using Dextrin instead of SGRS as the binder if you're rolling the stars because then you can use a water/alcohol mix, which speeds up the drying time and doesn't get too "sticky" during rolling.  

BTW I like the effect you got with 250 mesh - I'm going to try it in bigger shells with large stars with a longer burn time.
