Five desiccants - two month test with full results

This was a LONG video to make. But worth doing.

Note that the filled pods were dried at a maximum of around 90C due to the way the drying system works. It would have been better to have a system with metal containers and a higher drying temperature. But the results are still worthwhile.

Biggest surprise was the traditional cat litter (probably bentonite clay), which performed very well.
Biggest disappointment was the zeolite. I was expecting higher adsorption.
The rice performed pretty well for.... rice. And definitely smelled the nicest when being dried.
Another worthwhile test would be to see how low the desiccants can pull humidity in a sealed enclosure.

Note that desiccants like this are not designed to dry entire homes. They are for keeping the contents of small enclosures dry, with the recharging (heating to drive the moisture back out) being done in a room. The 1kg (2 pound) packs do a good job of keeping car interiors free from condensation damage if the packs are dried out regularly.
