Guess what Dick is doing?

I've been at home preparing for tomorrow evening's talk to Ponteland Camera Club.

Arth is a bit happier and had a good run on the exercise bike, plus two short walks in the village. Both were less than a mile, but it's progress.

During my second walk, I noticed that there were people at the village hall. It was the fourth day of an annual event which provides a certain liquid to sell in the village shop. Here is Dick supervising one of the processes, but do you know what he was doing? The extra of Helen in the kitchen will help you.
