A few years ago I came up with a demonstration for some high school students interested in chemistry. This demo is a modern take on a classic NMR experiment, using a low cost software defined radio to observe the FID signal as audio. In short, this demo allows you to hear the proton FID echo from the liquid sample inside the NMR magnet. This video isn't particularly geared towards explaining what NMR is, but instead is intended to convey that this demo is readily accessible to instructional labs due to the low cost of an RTL-SDR (or by extension other software defined radios such as the USRP, HackRF, LimeSDR, etc.
