I recently got a clapper for the Christmas lights I have strung up around my room. A clapper is a neat little product that you can plug lights into, and then plug it into the wall. If you set it up correctly, all you have to do to turn lights on and off is clap a couple times. It took maybe a total of ten minutes to finally get it working properly. My boyfriend and I stood incredibly close to the outlet the contraption was attached too, and progressively moved across the room to try and make sure it was listening from every corner of the room.
