A stalactite (UK: / ˈ s t æ l ə k ˌ t aɪ t /, US: / s t ə ˈ l æ k t aɪ t /; from Ancient Greek σταλακτός (stalaktós) 'dripping', from σταλάσσειν (stalássein) 'to drip') [1] is a mineral formation that hangs from the ceiling of caves, hot springs, or man-made structures such as bridges and mines.
Straws (stalactite precursors) in Gardner's Gut. Soda straw. A soda straw (or simply straw) is a speleothem in the form of a hollow mineral cylindrical tube. They are also known as tubular stalactites. Soda straws grow in places where water leaches slowly through cracks in rock, such as on the roofs of caves.

A stalagmite (UK: / ˈ s t æ l ə ɡ ˌ m aɪ t /, US: / s t ə ˈ l æ ɡ m aɪ t /; from Greek σταλαγμίτης (stalagmítēs); from Ancient Greek σταλαγμίας (stalagmías) 'dropping, trickling' and -ίτης (-ítēs) 'one connected to, a member of') [1] is a type of ...
A brinicle (brine icicle, also known as an ice stalactite) is a downward-growing hollow tube of ice enclosing a plume of descending brine that is formed beneath developing sea ice. As seawater freezes in the polar ocean, salt brine concentrates are expelled from the sea ice, creating a downward flow of dense, extremely cold, saline water , with ...
Over thousands of years a stalactite forms from the ceiling as the water continues to drip. When the water drips on to the floor of the cavern some evaporation occurs here also leaving a trace of limestone. Again over thousands of years a stalagmite is formed. A stone pillar is formed when a stalagmite and stalactite meet.
The Great Stalactite. The cave's most notable feature is the Great Stalactite. [3] This is one of the world's longest known free-hanging stalactites, reported to be 7.3 m (24 ft) in length. [4] This figure is a matter of some confusion, however, as it is also variously described as being 11 m, 6.2 m and 6.54 m. [5]
A helictite starts its growth as a tiny stalactite. The direction of the end of the straw may wander, twist like a corkscrew, or the main part may form normally while small helictites pop out of its side like rootlets or fishhooks. In some caves, helictites cluster together and form bushes as large as six feet tall.
