The cavendish experiment shows that even the very week force of gravity can be seen between two room scale objects. Even with the naked eye.

Corrections: 4:53 This isn't a fair comparison. Actually, if you changed the mass of the hanging masses in the experiment, it WOULD change the deflection angle. That's because the value of T in the equation would change. The torsion pendulum would oscillate more rapidly with lighter masses. Thanks James Gilbert.
