Colored Stars with tails

[Shizznt]

Hey guys, when I was on the internet I came across these pictures.

How do you get this kind of effect from colored stars? I've looked around on the internet, but I couldn't find anything on it and I don't know what the effect is called. Thanks. -Ryan

Those pictures show a slight time lapse, those are plain colored stars, but the slow shutter speed traces their trajectory on the image.Generally tails will be gold or silver from metals added to the comp. Other tailed effects can be achieved using matrix comets and married comets.

Yes, what nater says is correct. The shutter speed was slowed down for taking pictures of fireworks.

 

To add a trail of sparks behind a color, generally add Titanium or FerroTitanium, both produce nice Silver or Gold sparks. Titanium can be pretty much added to any comp without affecting the stoichiometry of the oxidizers and fuels.

Okay, thanks guys I thought there was some formula that gave you that kind of effect. That would be really cool if there were star formulas like that!

Well maybe you should look at diadem stars, they can give you a quite interesting effect too

A tail is a simple concept, the material for the tail must burn more slowly than the bulk star matrix so that the star burns and the tail is bits hanging in the air left over from the star.

 

It can be that two mesh cuts of charcoal are used -airfloat makes the star 50mesh makes the tail. Iron filings of even 100mesh aluminium will make tails too.
