How often has this happened to you? You have had a tough day. You come home and sink down into a nice, hot bath. You are just beginning to relax when you remember that you need to make an important phone call. And your phone is a touch screen. If you touch it with your wet hands it can do immeasurable damage to your smart phone. What to do? What to do?
Well, alrighty then!
Perhaps I'm just old-fashioned, but it seems to me that unless you're the President getting an important call about the State of the Free World while you're bathing (in which case you probably have some under secretary who can field the call and dial the numbers on your touch screen for you) any call you want to make can wait that minute or two it takes for you to get out of the tub.
On second thought, if you were the Leader of the Free World you probably don't take important State of the Free World talks on a touch screen phone. You probably have some sort of fancy smancy satellite hook up that you talk to other world leaders on. Hopefully not while you are in the tub.
But I think my point stands.
This is a strange "invention".
