A neutron star is so dense and its gravity is so strong that if an object was dropped from one meter above the star’s surface, it would hit the surface at a speed of 7.2 million km per hour.
Also, a teaspoon of neutron star would weigh about a billion tons.
Of course, it would be impossible to scoop up a teaspoon of neutron star or to suspend an object a meter above its surface before letting it go. Still, I believe the math works out. Regardless, neutron stars are cool, that's a fact.
