comment Can non-conductive materials can be grounded by a wire?
The comb and you are a poor enough conductor that charge would stay on it for a time even with you holding it to ground. If you left the comb in good contact with the ground it would lose charge and not attract paper.

comment Why nuclear tests move under ground since 1964?
It also provides less information to the opposition. It's harder for spy sats to measure the yield and harder to collect any samples of the waste products to identify the weapon design or performance.

@User58220 Originally they hoped the Earth was uniform enough that any North-South line would work.

Probably depends on how accurately you can measure the mutual attraction between the students. Can you suspend one of them from a rope and measure g from the pendulum period?
