I was thinking of exactly the same thing. Using F = (G)(m1)(m2)(r^-2) m2 = 70 kg (a person, let's say) m1 = 0.016 kg (weight of a DVD) r =

Using F = (G)(m1)(m2)(r^-2) m2 = 70 kg (a person, let's say) m1 = 0.016 kg (weight of a DVD) r = 10 cm You get 7.48 nano-Newtons..so a decent bit above the minimum resolution, supposedly.. hmmmm so it may not exactly be outside of the realm of imagination.. maybe with a couple of these things..?
