00:00The blade is tightly wrapped with fabric and soaked in fuel.
00:04Next, it's put into a metal sheath with a flint.
00:07And as the blade is drawn out, the flint is struck by hand,
00:11producing sparks that light the fuel instantly.
00:14Now the fabric doesn't burn away, only the fuel does.
00:18So as the sword swings through the air, the fuel whips around with it,
00:22leaving streaks of flame behind.
00:25To put it out, the burning blade is slid back into the sheath,
00:28cutting off oxygen until the fire dies.
