- Step 1: Purchase a sprayer Purchase a compressed-air sprayer from a lawn and garden supply vendor. Choose a 1- or 2-gallon model with a spray hose that extends several feet and a wand that is a couple of feet long.
- TIP: Do not use a sprayer that has been used to apply lawn or garden chemicals.
- Step 2: Extend the hose length Extend the length of the spray hose by replacing the original hose with a length of flexible rubber medical tubing. Leave an inch of the original hose connected to the bottle and the wand, and then secure the rubber tubing to the ends with heavy-duty rubber bands or duct tape.
- Step 3: Fill the bottle Fill the compressed-air bottle with water, and then transfer the water to a large plastic bag. Place a second plastic bag around the first bag.
- Step 4: Hang the bags Use the rope and clips to hang the bags from a tree in a warm, sunny location during the day. The water will make the water warm, but not hot, in several hours.
- Step 5: Heat the water in a large cooking vessel Heat the water in a large cooking vessel over a stove or fire if you want hotter water. Transfer the heated water to the compressed air bottle, making sure it is a suitable temperature for your shower. Then lather up.
- FACT: Ancient Egyptians took indoor showers by having their servants pour hot water over them.
