Cave Pillar Experiment

While studying rocks and minerals and learning about weathering / deposition, build your very own stalactite! Kids see the formation of  "drip stone" in limestone caves caused by "precipitated water solutions" (calcium carbonate / minerals) in just a few days! New formations (stalactites) are created in caves due to mineral deposition. These formations take many, many, many years to form! For the scientific explanation of the diy stalactite in Steve Spangler's video, click here!
