Had my long lazy Saturday bath this morning, part of the pleasure of which is a good read. I’ve always been too worried about dropping my Kindle in the water (I have a tendency to fall asleep and more than one book has found itself afloat.)
So I tried this, and it worked perfectly. No condensation, no splashes.
I’m not endorsing it, just saying it worked for me. If you try it, it’s at your own risk.
