Washing Soda Stalactite – Cave Pillar – SICK Science! #084

This crazy cave pillar forms in days, not centuries. If you've ever ventured into a naturally formed cave, you probably saw pillars stretching from the ceiling to the floor. They're called stalactites and they take hundreds and thousands of years to form as precipitation drips from down from the cave's ceiling. In the Washing Soda Stalactite experiment, you'll cut the stalactite formation process down to just a couple of days.
