Difference between black goo in the urn and the black goo in the bottles

Just realized the bottles are inside the urn! what a plank!

Haha, yep the glass containers are inside the metal urns.

Is there any better name for the black goo cuz that name is just stupid.

How were the urna leaking out if the liquid was inside the cystal?

These are the Glass Vials that are held within the Urns/Jars and these are surrounded by a Slime Substance, that when the Weapon was Activated in Prometheus the Slime Seems to React with the Glass causing it to Melt and Mix the TWO Compounds together and cause them to Leak Black Goo.

It would be good if we found out more about the Engineers language, could read what is on the urns then. To be honest would be good if we found out more about the Engineers in general!

the goo oozes out of the urns when the pressure inside the room changed. or it was programmed to become active when organic matter, possibly a specific target species, was in close proximity
