Hey you want to hear about exploding bananas. But first the purpose of my project was to see if I can make potassium from home. I first cut off pieces of a banana peel and then put them in a container and then I torched it. Once the bananas have been reduced to ash I add water. Then I grind it up and then filter it . When I was done I was left with a yellow liquid. I got the most from the unripe banana. Someone could try to get pure potassium but it is really complicated.
