My work is almost completely theoretical/computational. But I'd really like to do a Bell inequality experiment just so I can personally see this (the best way to learn something is hands-on, right?)

What all do I need do this? I suppose I can use two lasers and polarizing filters, but how exactly do I emit just one photon at a time? I actually feel kind of stupid asking this; I don't even know the basics of how these experiments are performed. Is there something expensive I need?

I wonder if my physics department would let an engineering student borrow their resources...

I don't think that's possible. Those are not exactly table top experiments. Especially if you want to do it properly. Read the papers by Alain Aspect to get an impression of what's involved and then decide yourself if you feel up to it. –  Jonas Jun 19 at 21:31

A nice news & views article from Aspect published in Nature is available here: ece.rice.edu/~kono/ELEC565/Aspect_Nature.pdf –  Jonas Jun 19 at 21:33

The most expensive part will be the single-photon detectors (a few 1,000$). Then, you cannot use two lasers because the photon would not be entangled. You need an entangled photon source (usually a suatably pumped BBO crystal) –  Frédéric Grosshans Jun 20 at 14:19
