Demonstrations in my physics workshop this morning. I took about eighty photos, trying to get a photo of sparks, and didn't manage to get any - but my friend took only a few photos on his iPhone and got a spark. Unfair.

Finished off my spectroscopy lab today. It was good fun. Radioactivity next week, I think.

At student group this evening we watched the new Sherwood Pictures film, Courageous. It's pretty good, and not too cheesy. It focuses on being a good father, but the principles it talks about can be applied to any area of life.

God is great.
