Distilling water is so energy intensive that sometimes reverse osmosis (filtering) is better to remove the salt. Reverse osmosis still take a lot of electricity that they may not have. It might be the case that importing water is the cheapest option
I tried acrylic paint, but it prevents me from making adjustments afterward by gluing more stuff on. Maybe I'll try watercolor or felt

In general, I would glue 5 pieces of cardboard using paper to make the underside of the box. Then I'd put the items in and glue on more layers to fill in the leftover space. After finishing the top layer, I'd leave the items inside the box for a few days to dry and shrink
After that, you can add more paper to make the surface harder, or glue on anything you want.
It's made from cardboard and a bit of egg carton paper

My items does look much better when I use the brown paper from cardboard than when I use discarded white paper
There are basically 3 ingredients: cardboard, paper, and glue.
First I would make glue by mixing flour with water 1:10 and microwave it until boiling. I'd stir and scrape the bottom every 30 seconds for the first few minutes to avoid burning
The cardboard needs to be kept dry (unless you want to separate the layers). It can be cut pretty easily with a serrated knife. For the first few layers of this box, I cut the cardboard to match the shape of the items. For the final layers, I just took the leftover pieces and glue them on. It doesn't have to be perfect since you can add more paper later. However, cardboard - cardboard bonds seems to be pretty weak, and you can't put too much glue on it, or it will get wet and separate. So I use paper to bind them together.
To get the paper, I spray water down the wavy side of the cardboard (a strong hose seem to work better than a trickle). After that the layers should separate easily. Getting the paper wet and tearing it by hand will give it better edges than cutting with scissors. I would use big pieces of paper on flat surfaces and straight angles, then thin strips for corners and curvy surfaces.
If you need to cut out something from the piece, you can wait for it to dry and cut with the serrated knife. The first version of the box actually doesn't have the hole for the funnel, I actually cut it out with the serrated knife. Then I covered the knife marks with paper
Edit: you can use any cardboard without the glossy surface. The glossy surface doesn't stick to the glue.
Looks a bit ugly because I used different colors of cardboard this time
Yeah, sometimes I just let it sit there to cook. The insulation would retain the temperature for a while
I cut them with a serrated knife or scissors, then glue the pieces together
I did think of insulating my big pot too, but I don't use it very much. One time I made a big pot of spaghetti sauce for freezing and now I still haven't finished eating it.
The inner container doesn't com into contact with the food. They are sealed in their own bags
Sous vide bags containing the food I want to cook
Made from a big water bottle wrapped in several layers of cardboard. The whole thing is covered with brown paper, which makes the surface harder and look nicer.
The lid is made from 4 layers of cardboard and trimmed to tightly fit the container. When used, it's covered in a plastic bag for waterproofing
Shaping cardboard to tight tolerances is pretty easy: when dry it is suprisingly stiff; you can cleanly saw it through with a serrated knife, even at tiny shallow angles. You can also add more layers of paper to make it thicker.
Made from cardboard paper, wheat glue and filled with coffee ground
The coffee ground shrinks a lot when drying. I'd use cardboard layers instead if I had to do it again
Made from cardboard and paper and painted with acrylic color. It has bowed down a bit in the middle since then, but it's still fine otherwise.
