I opened up a Xmas present in advance. And what did I get - a stainless steel soap.
I read the instructions and washed my hands with a little water and rubbing my fingers against it after slicing some onions. Yes, it works.
Can anybody say why it works? Does rubbing stailess steel free electrons to oxidate sulphur ions on skin? What are different odors anyway - gaseous ions, perhaps? Is this similar to ionizer/ozone generator, but low-voltage?
