Select any seven-inch record and stick a small piece of tape on either side. Put the modified record on a turntable and place the tonearm close the taped area. Switch the turntable on and listen to the loop generated by the record skipping. Adjust the placement of the tape until the perfect loop is found and then make a 30-second recording of that loop. Take a photo of the altered record, documenting the placement of the tape. Any seven-inch record may be used for this project.
