Cheap optics is a great worst buy... but my funniest and most appropriate end was a "Solar Shower". Supposedly you hang these deals in the sun and you have a nice warm shower. Well, I hung mine, I laid it on the hood of a vehicle for 3 days and finally found out how it works best. The last night when we were ready for bed I threw it on the fire, telling my buddy I figured out how this works. It did heat the water, it burned up the damn thing and put out the fire for the night so the ranger wouldn't get mad. LOL I vote solar shower.
I disagree with you David, I've used one for over 25yrs. It has to be sunny!!!! If not you heat up some water in a pot and do it that way. When camping it is an essential part of my kitchen for washing and rinsing dishes,
