Eric over at SilicaGelPackets.com was kind enough to send over a couple of samples for us to run through the old mill wheel. Of course I was kind enough to snag one to stick in the Pelican case so I can see how long it takes the indicator to change colors. The neat thing about these canisters is that when they get full of moisture you can pop them in your oven for a couple of hours at 280 degrees and they will be ready to go again... or at least they will after they cool off for a little bit. Make sure you read the directions and even though the gel is non-toxic, you should really keep it away from children and pets.

The bottom line is that you need this stuff to keep your precious toys from turning into paperweights. Those dryboxes keep moisture in just as well as they keep it out so you are going to need something to keep them dry on the inside. This little canister works for cases up to about three cubic feet and should handle most people's needs for small to medium equipment cases. SilicaGelPackets.com doesn't stop there, they have a whole range of products for keeping things dry including silica gel in bulk. Think big, like houseboat big.
