  • It's the twisting force the forks exert on the toothpick that balances their weight. If it was as simple as finding the center of gravity, there wouldn't be a restoring force which can create harmonic motion. Give the forks a tiny push down with your finger and watch them swing up and down like a pendulum. The torque created by the forks is what balances the weight of the forks, not the length or mass of the toothpick.
