As my main water source in camp, I usually carry a Nalgene Canteen. For a long time, I have been hanging it from a low tree branch with nylon straps and then tilting it with my hand to make the water come out: almost like a sink. This proved to be very convenient since it had a large capacity, weighed little, and rolled up for compact storage. 
Eventually, I found that the addition of a splash guard in the mouth focused the flow and controlled it so I didn’t waste so much water; however, there was still one thing that annoyed me. Since I do most of my backpacking alone, there was no one around to tilt the Canteen when I wanted to wash both my hands at once or use both of my hands to wash a pot. It was awkward to soap up one hand, tilt with the other, then repeat for the other hand. Likewise to effectively scrub a pot. What I wanted was a lightweight, convenient, hands-free source of clean water for washing and filling.
Basically, it’s the same setup as my usual “kitchen sink” but with a length of parachute cord attached to the corner of the canteen and the other to the ground that you step on (which tilts the Canteen and makes the water come out) making it possible to wash both of your hands at once or fill a smaller water container hands free. It weighs a little more but the convenience is well worth it if you’re going to spend a significant amount of time in the same camp (especially if the water source is far away and you have to haul it back to camp). Here is how to make your own.
Traveling to and from your camp, this system is very compact. Simply roll it up (make sure the cap is off to release all the air) and lash the cord around it to keep it secured.
While relatively light for the luxury, I know some will see this as a superfluous contraption that is more suited to car camping. I only offer it as an idea to contribute to the overall body of knowledge and idea sharing of the hommade-gear crowd. For every idea there's a niche and just thought that perhaps there is a niche out there that would appreciate this idea. Feel free to write in with your versions, suggestions, or alterations.
