Bananas

I was curious if there is a way to store bananas to keep them from browning so quickly.
I kept bananas (a) laid flat, (b) in a bag, and (c) suspended for a week.






















Results:
The bananas in the bag kept the longest (apparently oxygen causes bananas to brown).
Bananas laid flat and hung basically browned at the same rate.
Eat your bananas within 6 days of buying them (unless they are kept in a bag).
