      It depends on which part of the neutron star you were weighting. Assuming that a thimblefull is about one cubic centimeter, then with the density of the crust of a neutron star, it would weight about a tonne. However, if we were to take the core of the neutron star, it would be a lot heavier, around 100 billion tonnes, which is about the weight of 1000 mount everests.

      Sorry, I know hardly anything about astronomy.

      A neutron star has a density of around 3.7×10^17 kg/m^3. Let’s say a thimble holds about 1cm^3 of water. So the weight of a thimble full of neutron star is:

      3.7×10^17 x 1×10^-6 = 3.7×10^11 kg

      Which is around the mass of about 12 million elephants.
