How do you adjust the flame on a butane lighter?

To adjust the flame on a butane lighter, follow these steps:
1. Locate the flame adjustment screw or knob on the bottom or side of the lighter. It may be labeled with a (+) and (-) sign, or it may be a small screw.
2. Turn the flame adjustment screw or knob clockwise to decrease the flame height, or counterclockwise to increase it.
3. Light the lighter to test the flame height. Adjust the flame height as needed until you get the desired height.
4. If the lighter has a safety lock, be sure to disengage it before lighting the flame.
Always use caution when adjusting the flame on a lighter, and follow the manufacturer's instructions to prevent accidents or injuries.
