What practical experiments on quantum mechanics can be done at home?

Question

Physics

I am writing a project work on quantum mechanics. With the theory and presentation, the issues are resolved. But without some practical experience, the work is unlikely to be appreciated.
Hence the question: what kind of experience can I deliver/pretend to deliver?

Answer 1

At home, you can build a cloud chamber. And how to connect it with quantum mechanics, you should know better than me)
In addition, at home you can check the properties of a photon, both a particle and a wave) At home, you can pour
a little nitrogen onto a high-temperature superconductor and check its properties .
some magnetically hard material, as far as I remember, there we work with the spins of molecules, which seems to be related to quantum mechanics. When demagnetizing, you can see that we have some hysteresis, its nature is described by quantum mechanics
Well, of course, you shouldn’t play with the fluidity at home, but you can bring CO2 to a supercritical state. True, there seems to be no quantum mechanics here, but the experience is interesting.

Answer 2

At home, you can only experiment in quantum physics - you pass the light of a neon or fluorescent lamp through a prism and get a discrete spectrum
