Georgia for iMore:
Inside the iFixit Thirsty Bag you’ll find two “molecular sieve packets”. Each of these contains powerful liquid absorption material that, according to iFixit, can reduce the atmospheric humidity to 1% RH and suck up pretty much all liquid inside your device over night.
Sounds like a fantastic piece of emergency kit to keep in your house and for $6.95 it seems like you can’t go wrong. ((I ordered 2.))
