Sonometer recital(+ Shah)
It's not every day you can get a bit of international mindedness into your physics lesson and I have to admit this example is scraping the barrel. I usually like to show off my sonometer skills by playing harmonics but this year I just couldn't get it right. Must be my age. Luckily Emrys came to my rescue with a recital of some classical Chinese music. No harmonics (except the first of course) but plenty of tension. Shah as usual tried to get in the picture but I managed to crop off his head. Try harder, Shah!
