I'm eating a banana right now. It is very delicious and provides necessary vitamins and nutrients for aiding in the dispelling of this nasty cold I have had for the past 8 days. As I was walking up the stairs to go eat it, I dropped it. Exactly where it hit the stairs I discovered was bruised after I pealed it. Already, just seconds after I had dropped it, my banana had become browner in the one spot. To see if the reaction was really this fast, I put the skin of the banana back against part of it and flicked it repeatedly. When I pulled the skin back again I noticed that immediately there was a bruise visible. I am now curious as to what exactly takes places when a banana bruises, the chemical and structual changes in the fruit. Does anyone know?
