Evidence of Qi?

I did this experiment two years ago in trying to convince my wife to take up qigong. I took two mandarin (teochew) oranges on Chinese New Year day and placed them in my living room. One orange, I left alone, untouched. The other, I emitted qi to. At the end of six months, the one which I left alone was shrivelled, mouldy and looked nothing like an orange, that I had to throw it away. The other, still looked like an orange, except that it was lighter. To prove my point, I stopped giving it qi after six months. Within a week, this orange had degenerated, rot like the earlier orange. Why? I don't know. You tell me.

Below are pictures of two oranges. The one on the left was not fed with qi. The one at right was given 10 minutes of qi daily. I would hold it on one palm while ther other emitted qi to it. This session was carried out after my daily round of qigong.

Is there any difference? You tell me.

We shall bring you another set of pictures soon in a week or so to determine the progress of both oranges.
