I didn't know colour affected it. I knew HEAT affected it. Surprisingly, hot water freezes faster than cold. Beats me why though.
I'm doing a science fair project on does the color of the water affect the time it takes to freeze, can i have some statements on that?
Be a little more specific perhaps.
Maybe the effect on the freezing point of water containing various water soluble dyes.
And I picked this site at random as something that might give you ideas.
