A 4 L Erlenmeyer flask is charged with methanol. An activated platinum wire is lowered into the flask. The wire glows where methanol and oxygen are reacting, and immediately sets off a whooshing conflagration.
The wire continues to glow, a combination of convection and diffusion causing the air/methanol mixture to oscillate between a slow burn and periodic flash over.
