Although the phase diagram of bulk superfluid 3He is well known, novel superfluid phases are expected under conditions of spatial confinement. In this talk I will discuss a couple of experiments designed to investigate the physics of this system. The confinement geometry, in this case, is that of a flat slab. Following the rationale behind this research and a – somewhat mild - theoretical introduction to the physics of superfluid 3He in general, and confined superfluid 3He in particular, I will show some aspects of the experimental research. One of the experiments to be discussed will be a Nuclear Magnetic Resonance (NMR) experiment, which explores the magnetic properties of superfluid 3He. The other experiment, a torsional oscillator, is concerned with the flow properties of the superfluid. I will discuss both of them in as much detail as possible within my time allocation.

... And, yes, there will be (a few) results; hence the word facts in the title.
