Here's a brief explanation of his experiment.. So firstly, he is not blowing out the air..If he do.that, the ball will ofcourse fall down from the funnel... He has just sucked the air from the pipe for 2-3 seconds and the balls remains stuck in the funnel... And I don't meant that he is doing wrong, but maybe most of the people might try to do this with wrong techniques... So, when he sucks what happens is that, He has created a low region inside the pipe and the funnel.. As the pressure outside the funnel is higher than the pressure inside the funnel, the pressure difference creates an upward force on the ball, pushing it up into the funnel.. As long as you try to maintain the suction, the pressure difference remains and the ball stay stuck in the funnel.. No Logic Or Magic Is Happening Here...It's Only Physics That's Happening In The World Around Us!
