light through liquid

Last week the challenge was to portray a traditional still life scene of grapes, glass of 'wine' (double strength apple and blackcurrent squash did the trick), chunk of cheese and a candle... in chalk pastels and everyone did really well.

This week we'll go for some brightly lit coloured liquids in various clear containers - to be captured in watercolour or other paint medium
OR
a white 'marble' (or plaster and fibreglass) greek bust -to be captured in white anything on black paper.
