Travel Theme: Liquid

Alisa’s challenge this week is liquid. Below are two shots of soda straw stalactites being formed. Water from last night’s half-inch rain slowly worked its way through the concrete in the deck, leaching calcium carbonate ¬†and adding tiny amounts to these hollow stalactites before the water droplets fall to the ground. Although they can grow very long when left undisturbed in caves, the longest of these dissolving deck formations reached 2 inches before falling to the ground.
