Dunno what it was? The granite layer was easy. They also went through water, it was once a sea because it had fossil species found in oceans. But then they must have hit a magma vent. Supposedly molten mushy harden rock, or rocks that were otherwise scree, and the drill couldn't bore through. The heat was way too high on initial study for the depth. The amount bored through is the furtherest documented humans have been to date. But barely scratched the surface despite being almost twice the height of Everest. It proved a lot of past theories and inner earth models wrong, and the bores are still being studied, but the hole is sealed shut.

I was being entertaining, but yes it could've been the plastic?

The joke is they use the PVC, plastic, to make artifical reefs, they're really doing this to help the reefs, make the plastic ones, and every aquarium is full of plastic, rocks, coral, and plants.

But OMG it's killing the reef???
