Here is a little teaser,
Write the words, CHOICE COD on a piece of paper, in uppercase. Hold it in front of a mirror, upside down, the piece of paper, not you or the mirror. You could, of course, hold the piece of paper the right way up, and turn your self and it upside down......?
Any way, the reflection will read, CHOICE COD. clever huh?
The word, DIOXIDE, also works
PS. I hope this not too complicated for Borderstone
