Dry boxing?

[oooo35980]

So this is my latest awful idea, I'm going to get a Tupperware, put in some baking soda, put a hygrometer in the Tupperware and stick the thing it the fridge, when the humidity stabilizes I'll put a cigar in it and pop the lid on. Then I'll take it out of the fridge and as long as it's air tight I should have a nice little dry box until I open the lid. The baking soda is to absorb funky fridge smells.

I want to try this first because I don't want to go out and build a low RH box for Hawaii when I'm leaving here in April anyway.
