Here is a simple way to wash your hands with the help of gravity. It works like this. The jug of water is suspended from a tree or something alike. A section of vinyl hose is connected to the spout at one end and on a pivoting arm on the other. When the hose is brought lower then the water level in the jug, gravity forces the water out. When the hose is brought back above that level, the water stops flowing.
Step 1: Make the Cradle
Many 2.5 gallon jugs have ribbed sides. These ribs are going to be used to help hold the cord cradle in place.
Take 10’ of cord and tie a knot with the ends so you have a large loop of cord. Form a larks foot at both ends and slip them over the ribs of the jug. To help keep the cord in place you can put duct tape over the ribs.
Attache a hook made from a strong piece of wire onto the handle of the cradle.
