Color dye tests

Basit and I tested the prototype today, we added green food colour to the injected water. It is obvious that the entire polypropylene felt is not wetted in the current construction. Perhaps we will need a smaller diameter of the felt, we are considering reducing the diameter of the felt from 2.5mm to 2mm. We got some great video with the HDV camera (including Basit's nose), Basit can hopefully add some stills soon!
