The counterintuitive demonstration in the video is a beautiful example of the concept of center of gravity. It sure looks like the fork and spoon should immediately teeter off of the glass and crash onto the table. And its even more dramatic when half of the matchstick burns away but the contraption still balances on the edge of the glass. But its all physics.
