Bucket Chemistry

This turned in to a long day - running two lots of experiments in different buildings that both needed samples changing on a regular basis. Finished about 8 pm and went to the Union bar for sustenance. It was open mike night which is usually quite good but on this occasion there were some people whose singing ability was on a par with mine. Fair play, I don't have the balls to get up and perform in public, so good on 'em.
