Aqua Resin, or "Natural Aerogel" as they call it, is a jelly like substance formed near oceans. Scientists are unsure how it's formed, but its many uses might help us understand it more.
How (they think) it's formed is that this type of aerogel is unattended seafoam. It gets mixed up with some "paradox substance" (will specify what that is in the next part) and it turns this seafoam into a jelly like substance. The jelly washes up on beaches and it dries in 5 years (assuming it is undisturbed in that period), turning it into some weird-ass cloy of jellyfish and aerogel.
There's whole beachside fields of of this stuff lying around. Corporations are figuring out how to farm it.
It acts almost identical to normal aerogel except because it's a cloy with jellyfish in it, it has to be purified before using. Other than that. It is toxic to bugs, so a shredded up version of this aerogel is used for pesticides.
