Re: So you just dumped your cell phone, Iphone, small camera in the drink ....
Am I missing something? Not to be contrary, but if your going through the trouble of keeping this bag in your glove box, couldn't you just keep a bag of rice in your glove box? If your really desperate, it could then serve dual purpose as an emergency food (if you haven't already used it for drawing water out of a phone).
I don't carry my phone with me to the water, so I'm not up on how well the rice trick works compared to this bag so please excuse the ignorance.
