I had read about folks using pringles tubes as a mould, but there was a spilt between those who line it and those who don't. I'm guessing if you don't eat pringles often, then you'd want it to be reusable, so you'd want to line it somehow.
We eat pringles often enough that I've been able to collect a few empties, and I don't make loads of soap, so I'm not concerned about reusing them.
They are difficult to recycle here in the UK, and I don't think it's possible at all in some places, so being able to use them for something else before putting them in the bin feels good.
For this batch, I simply rinsed the tube well after shaking out all crumbs. I left it to dry for a day or two, then poured in the batter at a fairly thin trace. Once it was firm, I cut into the first part of the tube, then continued to open it up by tearing in a spiral around and down. The soap came out really easily, as the tube is lined with plastic, including the metal base.
Each tube will hold a little over a litre to the brim, but I suggest leaving enough empty at the top to get the spiral tear started. As you can see my recipe only filled about half the tube as it's a test batch, but if your recipe is larger, just pour until about an inch or two from the top, then put the rest into other moulds.
I've attached photos of part way through the peeling process and afterwards.
