Hi there, new here

Just wondering whether anyone here has any ideas for SFX you don't normally see in shows? All I can think of so far is cremoras...

[PyroSkitz]

urm yeh cremoras for exploding cars, small flash charges for gun shots possibly ? if im not mistaken, instead of actually setting of a fire dont they use smoke devices containing hexamine to make black billowing smoke out of buildings...dont think they usually use fountains on any show ive seen haha , any other ideas i would love to hear aswell...hope this list gives you some ideas to come up with ?

They use fountains, but not in the way you'd think. There are very short duration fountains, 1/2 to 1 second. They use them in explosions and creepy industrial areas. They look like a mine of sparks, but they're actually fountains.

Are you sure about hexamine producing black smoke? I've never heard of this being used for black smoke. I would think maybe naphthalene or anthracene instead if not actual black dyes.

oh mumbles are you talking about when "electricity" sparks they use an upside down quick fountain to represent that ? that would make sense... and ive found the recipe, and i read something about hexamine in... but the chemical i was looking for was Hexachloroethane


Magnesium powder – 19%
Hexachloroethane – 60%
Napthalene – 21%

also containing naphthalene...fair enough you where right hhehe

One favourite of mine is the 'laser hit' used in sci-fi - Andromeda comes to mind.

They seem to be small brightly coloured micro-star mines, probably only an inch in diameter. The effect is a vivid spray of colour projecting maybe a meter or two from the laser hit. It gives a much nicer effect than pure CGI as the stars bounce around a bit and the smoke can swirl around the actors.

You still have to paint the blaster beams in afterwards though

Wow guys, thanks very much, although I confused my wording a little, I should've said displays! Still interesting though! (should I start a new topic and let this one go forward? )

They are called 'Robotics' in the trade. See here:

Those are actually something I'm familiar with too, but they're constructed in different ways. The ones I was talking about were short duration fountains, they almost look like mines of sparks. Those are what I would call airburst, and are not fountains. Really, it's just a difference of if they're used on the ground, or from the ceiling or light fixture.

This is more what I had in mind.
