This flow visualisation was prepared for a laboratory writeup due tomorrow. After unsatisfactory results in creating a shadowgraph, and complexities in creating a Schlieren, I decided to fall back on this... a drop of milk in a glass of water :)
Time to do the write-up! ahhh! Then I realised that there's not really a flow, stuff up! Do another!
I should have wiped away those drops of water...
