SFX - sparks!? (4 replies and 2 comments)

Hello Roger and forum,

I wasn't sure where to post this question.

In an upcoming short film, I have a need for sparks to fly out when two hand-held objects are smacked together. It's a DAY shot, so the sparks don't need to be excessive, but they do need to be seen in a close shot.

I've looked all over and mostly find 'flash paper' type SFX, which aren't really sparks.

Any ideas?

Much appreciated!

You can glue sandpaper on one side and glue cigarette lighter flints on the other. You need to slide it rather than bang it.

Alternatively, a firesteel lighter hidden from view or taped on create plenty of sparks. Another way is to glue toy gun caps to both items and bang them together to ignite the caps. There are many ways but it does need a lot of practice to make it look right.

Mike - you're the best!

Thank you mate! I had a feeling you might have a good solution for this. You seem to have an encyclopedic knowledge of all things film related.

Really, thanks so much. I'll experiment with all your suggestions and see which technique fits best.

cheers.

1. Sweeny Zirc (zirconium) Hits fired from a paintball gun.

2. There's a new product called an esquib from esquibs.com. I've never tried it, but it seems good (and cheap).

3. An electric Le Maitre squib from https://www.lemaitreltd.com/products/»

Simon,
There many ways you can achieve these effects, it’s just a matter of experimentation
to get it to look right and that takes time, which nobody seems to have these days.
Hope it works out for you.

I always add them in post. When you have some action essentials or so, you put them in the project and put the blending mode on Add. 

I think that's the easiest way.
