I had a look at that article out of curiosity. Aside from the intention, I also find both the quantities and the items strange. Haven't they heard of candles? Have they really thought about the quantity of water needed? Why is a whole litre of vinegar included?
But most of all they appear to have made a glaring error in the amount of toilet rolls required. Out of four people, if just 2 are female, that's a hell of a lot more bog roll required...
The list stipulates 800g of chocolate. I'm partial to a bit of Toblerone. Best get some in before supplies dry up.
