How do you get air bubbles out of a thermometer?

1. Gently tap the thermometer. Hold the thermometer vertically with the bulb at the bottom and gently tap it against a hard surface, such as a table or countertop. This can help to dislodge any air bubbles that are trapped inside the thermometer.

2. Gently swing the thermometer. Hold the thermometer vertically and swing it gently in a circular motion. This can also help to dislodge any air bubbles that are trapped inside the thermometer.

3. Hold the thermometer upside down and squeeze the bulb. Hold the thermometer upside down so that the bulb is at the top and gently squeeze the bulb. This can help to force any air bubbles out of the thermometer.

If you are still unable to remove the air bubbles from the thermometer, you may need to replace it.
