These two gallon ( 8 liter ) containers are available for free in much of the world. They contain isolated protein and other things that bodybuilders use. There are specialty vitamin shops and bodybuilding stores that
sell lots of this stuff. The first store I called, said they have no use for empty containers, and that's where I got mine.
These containers are food safe, as far as plastic can be food-safe, they have a good lid that doesn't leak when tightened normally, without having to twist very hard. Most importantly for
water heating, they are black. Don't tighten the lid, when using them for water heating. Water and Air, need room to expand. I squeeze a little bit of air out, as I tighten the lid, so that there's room for expansion.
This is the perfect amount of
hot water, for an outdoor
shower. Or an indoor
shower I suppose. Set a couple of these in front of the picture window, and you're good. When placed inside a big, clear plastic bag, they will store heat even better.
Also a good amount of water for washing a batch of dishes. When completely filled, it weighs 8 kilograms, which is about 17.5 lb
The dash of my work truck has been used for this. When faced into the afternoon sun, this is almost always the hottest spot in the neighborhood.
Other than when I have a bath, this is about the amount of water needed for a variety of tasks.

Medicine ball washing machine.

The containers are also a perfect size for a small washing machine, where the only moving parts, are your body.
People pay good money for medicine balls, which are heavy rubber or leather balls , used for exercise. I use my washing machine with 5 liters of water in it. That's 5 kilograms, or about 11 pounds. Then there's a couple pounds of clothing. A container this size, is good for about a dozen pairs of socks or underwear. It's a nice size for gripping. I suppose it could be put inside a pillowcase, that has a little ball sewn into each end, for a handle. I have used it for side to side chest exercise, curls and whatever you call that thing when you swing something behind your head and then back in front. You can do pretty much anything that is done with the medicine ball, except for throwing it to your partner. Bad idea. I have had no issues with leaking, although it looks like the seal may wear out, and require some spray rubber.

Many kids need to get some exercise. Fill this up, and tell them they can watch TV, as long as they do a load of laundry while they're at it. I did it last night, until my roommate had seen
enough. The sloshing sound doesn't seem to bother the person getting the exercise.
That's about it. Free 2 gallon
solar heaters, which easily become small washing machines.
For clothing that is heavily soiled, put them in cold water, with the appropriate amount of soap, and mix it up for a minute. Then leave it in the sun for the day, and in the late afternoon turn the machine on.
Probably not the best way to wash a horse blanket, but very suitable, when we run out of socks, but don't have enough other stuff to warrant a trip to the laundromat or the basement.
Very delicate things, are unlikely to be harmed inside a smooth container like this.
This could be the perfect spot to do the first washing, of anything that might lose coloring and spread it to other garments.
