Banana blowing balloon

Friday, October 19, sunny

Going home from school today, I made a small experiment myself, called "Banana Blowing Balloons."

The materials needed for scientific experiments are: banana peel, balloons, rubber bands, and flower pots. Now, let me take a look at the experimental process.

First, put a banana skin on the balloon mouth, then tie them with rubber bands, then put the tied "banana balloon" into the flower pot and place the flower pot in the sun, so our experimental device It's finished. What interesting things will happen next? Don't walk away, let us witness the miracle together.

After the "banana balloon" in the pot is placed for one to two hours, the careful person will find that the balloon is growing slowly. Over time, the balloon is blown up by the banana. This result indicates that the experiment was successful.

Magical! If you still don't understand why, then I will answer it for you: In fact, we all know that fresh banana peels, if exposed to sunlight for a long time, will slowly oxidize, in the process of oxidation, Will produce a lot of carbon dioxide gas. When the banana peel is tightly placed on the balloon, the carbon dioxide gas generated by the oxidation of the banana skin slowly gathers in the balloon, and the balloon is "blowed" by the banana skin.

Classmates, if you also like this little science experiment "Banana Blowing Balloons", then act now. See who's balloon is blowing fast and big!
