The towers grow from the ground towards the
ceiling. Such cave formations are called
Did you know?
Stalagmites that grow fast can only reach 1 meter in
height in 100 years. But if the water drips slowly
such growth can take as long as 10000 years.
Stalactites and stalagmites can join together into
columns up to 10 meters high. How long does it
take for such a column to grow?
