Helio Pressure Shower

Once it’s full of hot water, this is a pretty good little shower.
However, getting full of hot water is quite difficult. In the pictures it’s standing up right, but it can only do that when the lid is closed and it’s been pressurised. Otherwise it’s a floppy bag. So you need at least one hand to hold it up right. The lid is on a little plastic toggle, so it keeps falling back into place over the hole, so you need another hand to hold that out of the way. Now it’s quite large, so you are gonna need quite a large volume of water to fill it. If you have a hose connected to hot tap, I might wonder what you need the shower for in the first place, but if you really want to use it, use your teeth to turn on the hot tap, then pick up the end of the hose, again, presumably with your mouth, and aim it at the hole.
Now if you don’t have a hose connected to a hot tap, you are gonna need a very large pot, or something, to heat water over your camp fire. This will be more difficult to pick up with your teeth, so maybe hold the handle of the shower with your teeth and hold the pot with just one hand and pour in the direction of the open hole. Some water may splash on you, again making me wonder if you really needed the shower at all.
