We > Kocuiba , Vasic Dressler , Leonard , Alec Radzavatis & self used to go to a church near BLOOR & KEELE & play PING PONG ...Kocuida was the best ...He taught me how to SPIKE from below the table , by getting a lot of spin on the ball , making it curve as it flys through the air ...I realized later > I had learned the physics principle of AIRODYNAMICS which airplanes use to keep them aloft > Make the air go faster over the top of the wing by having the wing curved on top & flat on bottom ....Therefore the air becomes less dense on top & the plane must go up , the faster it flys ...Writing this > I realize these games should be used to teach these principles !!!
