 CONT: When Dan is taking a bath Mark/Luke brings in a tape and tape  recorder with something for Dan to listen to and puts it on a shelf  above the tub. While Dan and Mark/Luke are talking, Mark/Luke goes  to leave and accidentally pulls on the electrical cord with his foot  causing the tape recorder to fall towards the bathtub full of water  which would supposedly electrocute Dan. Mark/Luke catches the tape  recorder before it can fall into the bathtub full of water and Dan  is saved. The problem is that the electrical cord is very clearly  pulled completely out of the tape recorder and falls to the floor as  soon as it begins to fall. When we change to a different camera view  the cord magically has been reinserted into the socket of the tape  recorder, which is only 12 volts as evidenced by the AC adapter in  the plug in the wall which is shown in a camera shot when Mark/Luke  pulls on the tape recorder cord with his foot causing it to fall.
