Guys, the driveway's not gonna be a problem. That fact that I'm blue from the knees down may be though. I really thought this project out before I built and tested it. I should have given the same effort to figuring out how to turn the pump off once it started pumping dye. How I also got dye on my forehead, I'll never know. PaPa Smurf comes to mind.
Nice set up! A picture of you dyed blue would have been priceless.
