Tell us about yourself!
I'm in San Francisco. Unless you're local and can work quick we probably don't have time at this point as we are shooting this weekend.
This is the main action. We are filming it at 1000fps at 4K. We figured out a good option using pvc pipe with a cap and an inner projectile power by compressed air. I still think a small detonation might be a better option to get the types of bursts that I really want. But this seems to be working really well. I'll update the thread with the result soon.
