How to make an omelette

We need at least 4 eggs per omelette. First, break the eggs carefully into a bowl and season with salt and freshly milled pepper. Then beat them with fork. After this, heat the oil, not too much heat, just heat it. Then pour the eggs into the hot pan. Carefully tap the pan so that the cooked omelette moves and slightly overlaps the pan edge. And then gently fold this overlap in toward the centre it should only go one third distance. Now arrange your chosen filling in the centre of the omelette and finally, fold the other edge in towards the middle.

How to change a spare tire

First the nuts on the wheel should be loosened. The second step is to raise the car with a jack. Next, the nuts are removed and the wheel is taken off. After that, the spare wheel is put on, and the nuts are replaced. Then, the car is lowered to the ground. Finally, make sure the nuts are completely tightened before you drive away.
