This trick can be made easily using just 2 forks, 1 stick and 1 glass. Your eyes won't believe, but it actually follows the laws of physics. The explanation is that the center of mass of the system (forks + stick) fall around the middle of the stick, exactly on the pivot and that's the most stable position. Even for small displacements the system is balanced by a restoring torque. Moreover, the system remain balanced even if half of the stick is burned, because the missing weight of the burned stick is negligible in respect to the whole weight, then the center of mass remains in the same position.
