It's not like you don't have one or two to spare for an experiment now.

I've heard it said you can dry them out by placing them in an oven for a
while, moderate temperature for an hour or so.  I'm not sure to that applies
to those you've used as a teabag, but I can't see why not.

The bags themselves might not like being dunked, being some sort of paper.
As usual, I can't find one now to try it.

Wikipedia linked to this, <http://www.desiccants.cn/products.htm>, absorbs
40% by weight, and their drying guide is a bit better than "shove in oven
for a while".

BTW, you mentioned florists use the cystals, why?
