The material that collects in the cup can range from pale greenish-yellow, watery liquid to a thick black tar.

Young specimens are edible if a large clear watery liquid comes out of it.

Even lighter still are the watery liquid hydrosphere and the gaseous, nitrogen-rich atmosphere.

There are also small stalactites, and unusual stalagmites that have the appearance of barrels, all of which are coated in an opaque watery liquid known as moonmilk.
