	<strong>Question:&nbsp;</strong>Allow me to set the stage: &nbsp;You&#39;re on a walk through the woods. &nbsp;It&#39;s wet. Autumn lake-effect rain and snow falls in temperamental waves dampening everything. &nbsp;Looking up from the trail you notice something white on a pine tree. &nbsp;Snow perhaps? &nbsp;You walk closer to investigate. &nbsp;Bubbles! &nbsp;As you look around you spot several more trees all exuding similar bubbles. &nbsp;What is going on? &nbsp;Why are bubbles forming on the bark of these pine trees?</p>
