#VeritasiumContest - Impossible Domino - Counterintuitive behavior of two dominoes

This video shows the counterintuitive behavior of two special dominoes and thus the principle of energy conservation - center of mass - lever - angular momentum . This video is not a fake, although it seems impossible that the right domino regains its complete potential energy, which it had at the beginning. Perhaps someone who is familiar with the matter would like to explain the physics that take place in the commentaries? The domino stone that was hit first stands up again after the second domino stone has fallen over. The concept, design and engineering was invented by viralvideolab. The parts are available for 3d * .stl files on thingiverse. This video takes part in the #VeritasiumContest competition. Subscribe: VeritasiumContest:
