Is it possible to use a ping-pong ball instead of the body that is proposed to be used to make a pendulum?

Is it possible, to make a pendulum, instead of the body that is proposed to be used in work, to take a ping-pong ball? In this case, it is not possible, since it is meant to be applied in a pendulum. The ping-pong ball will be affected by the force of air resistance, which will introduce a very large error in the experiment. In part, this is possible if the experiment is carried out in an airless space, but the mass of the ball is comparable to the mass of the thread on which it is attached.
