If you only need a small amount, you could buy
seaweed (called "nori") at an Oriental food store,
and a small packet of them is included with
the seaweed. I'd suggest the "Korean style"
seaweed, usually sold in packs of three containers
for about USD $1 per pack. That'll get you the
most cobalt-doped silia gel for your money.
