I've tried both! I even treated our church to a whole new box of it
because I just could not stand being faced with dried out and useless
Oasis. If you soak some and don't use it, or if you want to preseve
some you have used, you MUST keep it wet!

Once I've got some spare time(!) I'll run a trial on it. My wife has a
box of the stuff she has never used. I'll weigh some a few minutes
after immersing and draining, let it dry (will a month be long enough?)
and immerse, drain, and weigh again. Should give a definitive answer as
to whether or not it will take up water after being allowed to dry.

I wouldn't waste a good block of Oasis.
I've used the stuff for over 30 years and have never been able to re wet
it properly, not even adding a drop of washing up liquid to it,
when still fresh you can sometimes turn it upside down and re use
whilst still wet but you can find air pockets.
When doing dahlia displays at flower shows I could use around 30 blocks
at a time on a large display, the best thing was to sell off the whole
basket of flowers, basket, oasis and all..
Whilst still wet you could try cutting it into smaller blocks and try
rooting cuttings in it.
