Fresh Bananas Anyone?
Did you know that the banana is the only fruit that never faces an insect attack? But it contains high amounts of reacting agents that make it prone to fast decaying. Strangely, aluminum foil can slow down its rotting process by breaking the air contact.
Putting aluminum around its top stem will slow down the process of decay. The foil will slow the reaction enough for you to enjoy the stash of bananas for days, even a week or more.
