Apparently we can't trust node meta to return
the same data to us that we just pushed in for
a few seconds, so check an in-memory cache
first and only use the meta for newly loaded
areas.
Bash gravel down into ash to produce dry aggregate.
Dampen the aggregate to produce wet aggregate. The ash chemically
reacts with gravel to produce a cement.
Let the wet aggregate dry and it will cure into smooth-stone.
It will tend to flow and wander if left uncontained though.
Water is now squeezed out, can be reabsorbed, BUT might disappear
before being reabsorbed anyway. The original sponge can be
removed, though, and the water will just disappear on its own
after the timeout.
Pummel a sponge and it will release water if there is space
nearby, though it will be reabsorbed by the sponge in a few
seconds.
This CAN be used to wet other sponges (i.e. to have a managed
supply of water if working far from oceans) but CANNOT be used
to create infinite springs.
If the original sponge is removed (and there is no other sponge
to absorb the water) then the water will be removed as well.
