because you can stop them with your finger and you can’t stop bullets with your fingers. He has a mouthful of peas and blows and the peas are coming out. We stand over here and we put out finger in the trajectory of the peas and we come down on it slowly and we find that if we touch the trajectory of the peas that the peas will deflect. That is fairly simple. We find that if we put our finger deeply into the trajectory they will deflect at a sharper angle. We learn that balls in linear acceleration are deflectable.
"Now we come back to this man who is spinning and he has these steel balls and he is spinning around in front of us here. As these balls are going by me, if I touch one of these balls I’m going to learn that it deflects. So I am going to put my finger out and touch the ball as it goes by and the first ball goes by and it deflects. The next ball comes by and it is deflected. They all come around quite rapidly and each get deflected. Because however these balls are not free, they are attached by wire to him, so they go down in the deflection to a circle, down here, and then they come up here and start taking a new pattern. As a result of my touching them here the plane of the wheel turns out like that. For the moment then I break the wheel by this deflection. It is quite tough on the wheel to be bent there. Half of it is deflecting out like this and the part that hasn’t come to
