Hi there, big fan for long time now and happy to maybe contribute something now. I am so happy to finally pull this trick off. It took hours and hours of trying. The props are called cigarboxes and the scene is not that big, accept in Japan it is quiet popular. I don't want to exaggerate but maybe this is a world record. So far I searched the internet for anyone who does this trick with more than 5 Boxes but could not find one. So I thought maybe 7 boxes could be something worth seeing. Guy doing a trick where he throws a stack of boxes in the air then grabs the one at the top and then place it at the bottom of the stack to catch the boxes. There is a slow motion replay for the seven box attempt.
