if I put a banna in the fridge will it turn black tommorow?
Answered by Ms. Sue
Try it and find out.
Answered by Dr Russ
An interesting thing to try is does putting other ripe fruit with the banana speed up the 'going black' process? Alternatively does putting a ripe banana with other fruit speed up their ripening?
