Some people have weird needs. Don’t ask me why you would possibly need to type while completely submerged. I don’t think typing an essay will be at the top of your priority list if you’re either a.) swimming or b.) being flooded out of your home. But hey, to each his own.
If for some odd reason that you want to blog from the bathtub, just because why the hell not, the Devlin Electronics CleanKey keyboard is waterproof and fully submersible, even when it’s still plugged into a power source. We imagine it also works great if someone in your family has leprosy and you need to thoroughly need to clean the keyboard after each use. For extra protection, you can just wrap that shit in Seran Wrap.
