The work is dedicated to the research of the basic peculiar qualities of an unusually moving pendulum which is made of a candle lighted at both ends and with the rotation axis in the middle. Thanks to its similarity with lever scales, such pendulum may be called a lever one. Because of the candle`s fusing the length of the pendulum shoulders reduces. So the full name of such pendulum can be: ”A lever pendulum with the reducing shoulders”.
