ok, yes, I do watch TV on occassion.
On a recent episode of "Man, Woman, Wild" , the lost and stranded couple actually purified their water by boiling it in a used plastic (PET) water bottle over an open flame.
Bottle did not melt, water boiled inside.
The scientific explanation sort of made sense ... but ... has anyone else actually tried this.
Does it work ?
Need to be really careful ?
