Call me a heretic but I haven't seen evidence of them sneaky Egyptians inventing the first hoses, especially since given the above they need to be at least semi transparent. What were they using intestines all neatly stitched together?

I could buy the reverse process using a channel with water to establish a level and using a stick to measure up off it but hey we all know the aliens built those pyramids smile
