One of my Old Guy medicines has an elaborate desiccant container:
Being that type of Old Guy, I weighed the container when I emptied the bottle, then left it sit in the kitchen cabinet with the scale for a week as the weight slowly increased.
It started at 2.38 g and stabilized at 2.56 g, so it absorbed 0.18 g of water from the air after it got my attention.
Peeling the label revealed an obvious joint:
Looks like HO-scale coal in there!
The desiccant weighs all of 1.20 g, so it absorbed something more than 10% of its weight. That’s less than I found with silica gel, but I don’t know the starting weight or how much moisture it already absorbed.
A newly opened pill bottle disgorged a container weighing 2.42 g. The initial weight obviously depends on many variables, none of which would be tightly controlled.

Don’t let the old man in
Keep him in the bottle!
Something interesting I discovered is that if you blow through one of those desiccant packs they have a significant exothermic reaction.
One notch below “venting with flame”, I trust … :grin:
If the package wasn’t present, the heat of the air coming out suggested it could be painful. No flames, though.
Phil Desiccant, I remember him, we went to high school together.
I feel deprived! None of my old-guy medications need desiccant, so I’m missing out on geek-nirvana. [grin]
OTOH, I did break down and buy one of the smaller Ryobi parts boxes to hold the backstock of medications. So far, I don’t need another one. [Crosses fingers.]
