It's all explained in any high school physics text -- maybe even in an 8th grade science text. Don't forget that the human brain gets involved.Take your son to a local library and study the issue together. It would be a great bonding experience!

When I first read the OB comment I went to a mirror then I raised my right hand to my right ear and it was still on the right side in the mirror image but holding a bottle of Listerine up produced the words backward. I'm looking straight into the mirror so my axis of perception has not changed. Why do the word on the Listerine show up backwards? >> Roy >> In a message dated 11/18/2011 4:35:43 P.M.
