Bitumen-based fuel

Okay kiddo, have you ever seen or heard of those big trucks that are used to carry rocks or heavy things on the roads? The black stuff that they put on the road is called bitumen.

Now, some grown-ups decided to use bitumen as a fuel for cars and other vehicles. They first heat up the bitumen to make it thinner and then they add some other substances to it. This mixture is called bitumen-based fuel.

When you put this fuel in a car, it burns and makes the car move. It works just like the regular gasoline that powers your toy cars. But, bitumen-based fuel is not used as commonly as gasoline because it's thicker and harder to work with.

So, in summary, bitumen-based fuel is a special kind of fuel made from bitumen which is used to make cars move.
