Holy sh..! What a point in question! Okay, I use as little as possible. They are mowing down the Sierra Mountain's old growth forests wholesale in Mexico to make TP. I'm still in a frame of mind of a guy with a septic tank, which gets expensive when overloaded.
I use about three sets of three sheets to wipe and maybe two or three sheets more, average. I then use water and a face towel to get things sparkling again. No skid marks here, even if I did wear pants. Nine to twelve sheets from Trader Joe's. Hmm, that reminds me, I'm down to one roll. I get a 24 pack, at I don't know how many sheets. One grand poop on average each morning.
I now have 15 TP rolls and three kitchen rolls, in my storage box. DF gave me two.
Prostate has me using generally one sheet per pee, which is better than flicking. I ain't counting, but that's probably 8 to ?18? trips to the john each day, depending on how much activity, water consumption, the temperature outside and whims of that too big prostrate system. I would guess that I get ten days out of two rolls, maybe more. DF and me under the same roof was much quicker. When we camp and backpack, she uses up her roll much quicker, as she wipes her nose more and uses like three sheets just to pee. Still, so far, I'm just getting a pair of rolls each week from her. So, give or take three or four rolls a week between us. Mine lasts longer, too, because I'm over at her place so much. The roll box is filling up slow, but sure. A 24 pack probably lasts me a couple of months. I thought to enlist my granddaughter and her household.
I think Bob has the right idea, if you have a goof water source.
Sounds like your burningman sculpture is growing quicker than mine. I do have a huge amount of packing boxes, etc. right now. I've got a twelve foot tube to anchor into stability that will probably shoot fire at the top like a rocket, if I plan it correctly. I'm making a special shelf just to store cardboard materials in the garage...
I like the way you set your tubes together.
We used to take a mixture of acetylene and oxygen, fill a balloon, or exercise ball with it. Then, attache it to the end of a stick of electric conduit in the air. Then, we'd let it drop at the fire as we ran for cover. Sounded like a cannon, shook windows all over the neighborhood and created a mushroom cloud 12 feet high.
