I'm relatively new to MMs, but so far, I think I am leaning towards making my own- silica gel is available is decent quantities, but I still have to find/make a container that will contain the gel and still allow air to pass...
I plan to remove the gel so that I can nuke it in the microwave without melting the container.
This solves several problems at once:
1) I am too lazy to nuke the MM on low power, on, off, on, off, on, off, lather rinse repeat
2) I am too cheap to keep buying new ones, plus the disposable mindset doesn't appeal to me
3) I'm too impatient to wait for the Dri-Rid or oven to dessicate the pinkies.
4) I likes the DIY route.
I've seen some websites that put the silica gel in resealable cloth bags. This might be a viable option. I've also looked for little lab vials and porous plastic, but they seem to only be available in bulk quantities.
I have some other ideas..

I think simply putting them in little ziplock baggies would work too since the bags don't have an airtight seal. I think I would probably have to get larger silica gel beads.
The white aquarium airstones might work. These are essentially porous plastic tubes that aerate the water in aqauria, but they might be too small to hold enough silica gel.
