When a physicist at a university turns their diagnostic tools to mundane every day things, rather than say quantum particle collisions, the difficulty of doing the experiment is usually going to be much easier. However it can have good consequences for the rest of us.
For example an Italian guy decided to take a look at how filter paper under an espresso puck affects the espresso. Here . This showed that the puck improves extraction and reduces channeling. It's a simple thing to do and it has helped me with making good espresso in the morning.
So I'm happy that this sort of research gets done.
