How Does Experiment Ethylene: Ripening of Banana Work?

Ethylene is a tiny message that bananas send to each other when they get ripe.

Imagine you and your friend are playing hide-and-seek in a big room. When one of you finds the other, you shout "Found you!" That shout is like ethylene, it tells the rest of the bananas it's time to get ripe too.

In the experiment, we put some ripe banana with some unripe banana in a bag and close it tight. The ripe banana starts sending out lots of ethylene messages, and the unripe banana gets the message and starts changing color, from green to yellow, just like when you eat a banana that's already started getting soft.

If we put all the bananas together, they all get ripe at the same time because each one sends out its own ethylene messages, making it look like they're having a big ripening party inside the bag!

Bananas are like little message-passing machines. When they’re green, they don’t send many messages, but when they start getting ripe, they go "I'm ready!" and send out more ethylene, telling other bananas to join in the fun.
