The article considers paradoxical results of metal chain movement that do not agree with classical theoretical models. We present the results of experiments with the falling U-folded chain and with chain fountain. The velocity and acceleration of chain motion were measured and estimated. The trajectory of the fountaining chain links has been investigated experimentally. A comparison of the experimental data with existing theoretical models is made.
