This might definitely be an option. I'll have to see if there are any obvious lines on the wall next time I'm in there.

The ink will bleed and indicate the high point of the water. It is like that chemistry experiment where you use a solvent to seperate black ink into a spectrum of inks.

You could smear the paste or rub the chalk or color with water soluble ink on the cord then tie it to something high and anchor it to the floor with a heavy rock or something. I think I might try this too. Great ideas!
