You ask the company if they would like an omelet cooked; then you break
four eggs in a hat, place the hat for a short time over the flame of
a candle, and shortly after produce an omelet, completely cooked, and
quite hot.
Some persons would be credulous enough to believe that by the help
of certain ingredients you had been enabled to cook the omelet
without fire; but the secret of the trick is, that the omelet had
been previously cooked and placed in the hat, but could not be seen,
because the operator, when breaking the eggs, placed it too high for
the spectators to observe the contents. The eggs were empty ones, the
contents having been previously extracted, by being sucked through a
small aperture, but to prevent the company from suspecting this, the
operator manages, as if by accident, to let a full one fall on the
table, which breaking, induces a belief that the others are also full.
