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.

comment How accurately can I expect to measure the gravitational constant with a club of college students?
@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?

comment Should a Faraday cage block a radio's signal?
@AndrewGrimm as long as the gaps are significantly smaller than a wavelength then they don't matter. That's why your microwave (15cm) has a mesh with 1mm holes in the door. But for high frequencies, and ultra low noise, it is difficult to make an effective screen
