A cool new trick

I figured out that if I push down and toward me on the edge of a cylinder (like one of the toy oil drums from my Hot Wheels stunt car set), it will shoot across the floor and spin like a top! It was a pretty cool discovery and I showed Dad what I learned. He mumbled some stuff about physics and friction and torque, then he sort of trailed off and walked away, scratching his head. Oh well. It was still a fun new trick.
