What if the bubble light does not bubble?
1. Make sure the bubble light has been on for at least 30 minutes (light is on inside plastic base) and is well heated. 2. Make sure the temperature of the room is over 65ºF. 3. Unplug bubble night-light and gently shake to mix the fluid Warning do not break glass vial, be careful not to hit it against other objects. 4. If this does not work, gently tap glass vial with finger (careful, vial is made of glass). 5. Bubble light should start to bubble after steps 1-4 have been completed.
