And the air-tight seal on the battery compartment can cause the flush button to bulge out when the air pressure inside the flashlight is higher than the outside air pressure. Changes in elevation, weather and temperature can affect the relative air pressure within the flashlight. You can improve tail standing by equalizing the air pressure inside the flashlight.
