I've done the vinyl tube in a bucket thing once. Accuracy was about +/- 1/2
inch due to surface tension acting on the inner surface of the vinyl. A
teaspoon or two of dish soap in the water improved it a bit.

Honestly, I did just as good with a 6ft bubble level going around the room
and didnt have to worry about getting the water all over the place

I need a water level. It seems you can make a one-person water level by
hooking one end into a reservoir. If anyone has done this, I'd be
interested in what they used for parts.

TIA,
