Dark fermentation

Dark fermentation is like when you make your yummy smoothies in the dark. Imagine that you have a big jar of mud and some tiny creatures (bacteria) inside it. You feed the creatures with your leftover fruits, vegetables, and other organic stuff. They eat and digest it, which produces gas and some other things like alcohol and organic acids.

Just like when you blend things in your smoothie maker, the gas produced is trapped inside the jar. The gas can be taken out and used as a source of energy for things like cars, homes, or even to make electricity. Isn't that cool?

So, basically, dark fermentation is a process where bacteria eat organic waste and produce gas that we can use to make energy. It's like recycling your leftovers into something useful!
