Can anyone recommend a good waterproof power strip? I only have one outlet (2 plugs) in my basement studio. It's right behind my wheel, and my wheel and my extra lamp are plugged into it. I'd like to be able to plug in things like my stick blender (for glazes) without having to unplug something else. But I'm guessing I ought to use something that will be safe (or at least relatively protected) from splashes of water and slip. Any suggestions will be greatly appreciated. Thanks!
