Mandarin Oranges

Last year, I did something similar - but only for about 3 months. This year, I am going to try this experiment till all 9 Mandarin oranges becomes rotten or dehydrated.

Since 3rd Feb, I had collected about 12 Mandarin oranges- straight from the carton, and left them on my cubicle divider. 3 has gone rotten within 2 monthsToday- 9 of the oranges are ALL looking as good as new. Some do feel lighter, but I have no way of confirming that as I did not weigh them before my 'experiment' started.

But if you consider that more than 3 months later, the Mandarins still looks as good as new, you have to question what do the farmers put on them. These oranges are not in leak tight packaging. They are in the office environment 24 x 7. And the office air-conditioning is only switched on from 8am to 6pm from Mondays to Fridays. It is a sauna during the weekends and on certain nights.

What in the world are in these oranges??
