Since curve tracers can go to large voltages, you can look at the I-V characteristics of things like neon bulbs. After playing with a bulb for a few minutes, I wanted to see if the photoelectric effect was observable on the curve tracer. Sure enough, you can see the effects on quantum mechanics in a cheap Neon bulb!

Here’s the video:
