oil drops

thought I'd try some indoor macro tonight as its been the first night for ages that I've not either been out or enjoying the weather on the balcony. 
Its still very warm but quite windy this evening. This is some olive oil in water in a bowl on top of a CD disc lit with a torch (having no old CDs here  may have sacrificed Michel Thomas French CD no. 1 , but hopefully won't forget so much that I'll need to go back that far!)   The drops do look big here but they really were tiny!
