After watching a few Youtube videos a few friends and I thought we'd give this a try. Basically you stuff steel wool into the end of a whisk then light it. Molten sparks come out and with long exposures you can produce some interesting results.
All was going well up until the moment a large blob of molten steel skipped across the ground and into a very small opening of my camera bag. My bag started to glow and very quickly flames were coming out. I had to fight off my mates instincts which were to upend the bag and shake the steel out, when I still had three lenses inside.
All images were shot in the art district of Shanghai.
