Laws of physics are fun. Just recall a plethora of toys like yo-yos or spin pens utilising inertia. Enthusiasts and curious visitors witnessed them in action at the fourth Russian Yo-Yo Contest in Moscow.
Participants, both girls and boys, some in their early teens and others proud parents, gathered to showcase their dexterous hands and perfect senses of timing.
Yo-yos dancing on strings, shuffling Diabolos, and more exotic toys dominated both the competition stage and the halls of the club.
