I did this one in the senior lab as an undergrad studying physics at New Mexico Tech.
I got to use a whole gymnasium for a weekend and used a laser beam projected across the gym to read out the torsion balance. Pretty cool that you can measure the gravitational constant [1] so easily, if approximately.
