Olive oil and water with blue and rose pink food colouring wedged between to sheets of perspex.
Wow, I was so amazed at all the colours that came out of it.
It was fascinating watching the interaction with the oil. This was the most fun photo challenge I've done so far- both art and science together
.
Taken last night, I had to wait nearly the whole month until hubby got back to cut up the perspex for me.
