These will not burn the mouth as charcoal will.

They should be picked up with a fork which will penetrate the pine coals, but not the charcoal, the latter being brittle.
Another method of eating burning coals employs small balls of burned cotton in a dish of burning alcohol.

When lifted on the fork these have the appearance of charcoal, but are harmless if the mouth be immediately closed, so that the flame is extinguished.
In all feats of fire-eating it should be noted that the head is thrown well back, so that the flame may pass out of the open mouth instead of up into the roof, as it would if the head were held naturally.
To drink burning oil set fire to a small quantity of kerosene in a ladle.

Into this dip an iron spoon and bring it up to all appearance, filled with burning oil, though in reality the spoon is merely wet with the oil.

It is carried blazing to the mouth, where it is tipped, as if to pour the oil into the mouth, just as a puff of breath blows out all the flame.
