I'm doing an engineering experiment soon and would like to be able to quickly dye water. The water is still (i.e. not moving) and I would prefer not to physically disturb the water as best I can.
What techniques could I employ to quickly diffuse a dye through water? I was thinking that electrophoresis could be a possibility. If so, what dyes (or what could I add to a dye) to help speed up the process.
Thanks in advance.
