It is called Stalagmite.
Stalagmite is a type of speleothem that rises from the floor of a limestone cave due to the dripping of mineralized solutions and the deposition of calcium carbonate. This stalagmite formation occurs only under certain pH conditions within the underground cavern.[1] The corresponding formation on the ceiling of a cave is known as a stalactite. If these formations grow together, the result is known as a column.

Stalagmites should normally not be touched, since the rock buildup is formed by minerals precipitating out of the water solution onto the old surface; skin oils can alter the surface where the mineral water will cling, thus affecting the growth of the formation. Oils and dirt from human contact can also stain the formation and change its color permanently.
The pointy things inside a cave are called stalactites.
A stalagmite is an elongated collection of minerals found rising from cave floors.
A soda staw represents the earliest stage of stalactites. A soda straw is like a thin tube attached to the ceiling.
Yes, stalactites do grow toward the cave ceiling. Stalactites form when mineral-rich water drips from the ceiling of a cave and leaves behind deposits of minerals over time. As each droplet of water evaporates, it leaves behind a small amount of mineral deposit, causing the stalactite to gradually grow downward from the ceiling.
== == A "stalactite" also known as dripstone, is like a stone icicle on the ceiling of a limestone cave. It develops when water, in which minerals (usually primarily calcium carbonate) is dissolved, drips though cracks in cave ceiling. As the water falls, it leaves behind microscopic amounts of the mineral. Over time, this collects to form an icicle-like structure. Note that a "stalagmite" is like an upside-down stalactite growing up from the floor. When water drips from a stalactite and hits the cave floor, there is often a microscopic mineral deposit left there as well. This deposit builds up over time. It is possible, by the way, for a stalactite and stalagmite to meet, forming a mineral column.
A limestone deposit rising from the floor in a cave is most likely a formation called a stalagmite. Stalagmites are formed when mineral-rich water drips from the ceiling of a cave, depositing calcite and building up over time. Over thousands of years, stalagmites can grow tall and take on various shapes.
This is called a "Stalactite"

That's called a stalagmite. A similar object descending from the roof of a cave = is a stalactite.
Stalagmite.
A stone column rising from the floor of a cave is called a stalagmite. It forms over thousands of years as mineral-rich water drips from the ceiling and deposits minerals on the cave floor, gradually building up into a column shape.
It is cave in a big natural deposit of salt.
False is is called a stalagmite

stalagtite
A deposit of calcite on a cave floor is known as cave popcorn or cave coral. It forms when water containing dissolved calcium carbonate drips or seeps into a cave and then evaporates, leaving behind calcite deposits in the form of popcorn-like or coral-like formations.
