1, take a small cotton ball, lay it flat and wrap it around one end of the toothpick. When it is wrapped, it is the wick.

2. Insert the wick in the middle of the nest of the cotton lamp, and the cotton on the wick should touch the bottom as much as possible.

3. Turn on the light after dark and pour a proper amount of salad oil into the nest. When the cotton on the wick is soaked with salad oil, it can be ignited.
