How to Make a Solar Shower

In the summer i set up a solar shower I rigged this thing where i i got a like a big plastic jar sort of that i guess said they had cooking oil or something in some restaurant i found it so i cleaned that out and painted it black. In the winter the winter is a little more complicated because i had this camping gas thing like this little butane tank with two burners  so what i would do then is hold on this big spaghetti pot to get water boiling. when to turn and not hit people but nobody could see who was under the mattress it was perfect it was like god himself had said i will protect you from embarrassment poor young english teaching guy yeah.
