A premixed oxygen-acetylene flame shows instabilities at its edge.

Ignition of an oxy-acetylene torch, filmed at 3000 frames per second. Ignition took 0.7 seconds, while the flame front traveled at 2.5 m/s.

A premixed flame propagates upstream from a spark source to ignite an oxy-acetylene torch, filmed at high speed.

Sparks scatter as an oxy-acetylene torch burns through a plate of steel.

Aluminum chips are ejected and fly through the air as the edge of a 3/4 inch plate is milled. Filmed at 240 frames per second by a CASIO EX-ZR 100 camera.

The light from sparks generated by grinding steel was refracted by water, reflected by a mirror, and then refracted again as it exited the tank. Shot with Arista Premium 400 ISO B&W film, using green and orange filters
