📖 Read the story
Scientists have a new way to make clean fuel. They use a special kind of indoor lightning called plasma. Plasma is a very hot gas with a lot of electricity. In the past, making fuel was difficult. It needed too much heat and made the air dirty. Now, scientists put natural gas into a small bottle. Then, they make a purple flash of lightning inside the bottle. This lightning quickly changes the gas into a liquid. This liquid is a fuel. We can use this clean liquid fuel to run cars and make plastic things. This new way is very fast. It is also cleaner because it only uses electricity. Scientists are very happy because this can help protect our planet. It looks like magic, but it is real science!
