discovered a really surprising thing today. today i bought some fruit for the netting to use in netting riccia down to rocks. Normally I look for green netting, but this time i got blue thinking, oh well itll be ok in a few days. The mad thing is, its almost totally invisible compared to the green stuff i normally use! I guess its to do with the light refraction in water absorbing the blue colour. bit of a random rambling, but heyho!
