Let bananas do the job

I read an article which stated that a gas given off by bananas can ripen tomatoes. According to the article, tomatoes which are put in a paper bag with one or two bananas in it will help to ripen the tomatoes. I don't know whether this is true. Perhaps readers can try it because I do not have unripe tomatoes to do the experiment.

I believe it will work because I can still remember how I put unripe bananas in a gunny sack when I was small and they ripened in a few days' time. It must have been the gas given off by the bananas themselves that helped them to ripen.
