The five-hundred-thousandth visitor was Yuqiao Wang, a 22-month-old infant accompanied by her mother and aunt.
The visitors were greeted by Deputy Commissioner Richárd Mohr and Deputy Director of the pavilion Katalin Szöllősi.
The Hungarian Pavilion has attracted a daily 10,000-12,000 visitors on average since it opened.
At the centre of the Hungarian Pavilion is the Gömböc (pronounced 'goemboets'), a self-righting object created by two Hungarian inventors. The Gömböc rights itself when in stable equilibrium, much like a roly-poly toy, but because of its shape, not because of its weight. The Gömböc is thus the first known homogenous object with one stable and one unstable equilibrium point.
