if you put pineapple in a bag it doesnot rot because it is not affect by the air in our atmosphere which other fruits are affected by
if you leave it in there it will rot...
You put an apple in the center right over the place where all the new leaves come out and then you put a bag over the plant. The apple will put ethylene gas and the bag will hold it in and it will cause the pineapple to want to produce a pineapple. P.s. make sure you do this when the plant is 12 to 18 months old. P.s.s. When you see it start to flower then you can take the apple and bag clear plastic bag off.
NEVER
For example pineapple... you use a plastic bag that you get from shops and you put your pineapple into the bag, tie it well and put it in a darkroom area. Wait for at least 5-7 days minimum.

This is a very good question. In fact, I had to do a science project about rot. So I used cornstarch in water. It actually does rot after a week or two. I put some of this mixture in a bag and left it in a container for a couple of weeks. After a while it started to turn green and blue. Sure enough it was rot.
in a bag because it can get real most in the bag.
Banana's, just like any other fresh food will rot in a bag. If you are trying to keep other food fresh, you should not put banana's with them (e.g. in a fruit bowl) because banana skins actually speed up the 'rotting' process.
Just put then in a dry spot (not in the sun) and do not water them. plastic bag tied tight works great too. A sealed paper bag is better a plastic bag will encourage rot.
Both will rot eventually, but the one in the plastic bag will rot first. The gasses that the banana gives off are kept inside the bag, thereby aiding in the breakdown process of the fruit.
in the plastic bag first
I am pretty sure bananas will ripen and/ or rot faster if they are contained in something such as a brown bag.
