 note = {We introduce an attractive demonstration experiment, ""Levitation of a ping-pong ball"", by cold liquid nitrogen. Liquid nitrogen in a PET (PolyEthylene Terephthalate) plastic bottle evaporates rapidly by being heated from the tap water around the bottle, and the nitrogen gas flows from a pipe which is attached to the bottle cap. A ping-pong ball floats above the pipe when the ball is put into the nitrogen-gas stream, due to the Bernoulli principle. We give some tips and important points for this demonstration, based on the experiences of scientific outreaches.},
