Thevapor patch will open the sinuses and allow a more restful sleep. It works. A paper signal mirror is from a burn cell I bought for a job. It was a piece of very heavy paper with a silver side. I tested it against a much shinier CD and the ever popular aluminum tape and it threw a stronger light. So I cut out small signal mirrors using a credit card for a template and used a paper punch for the sighting hole. They fit real nice in an Altoids tin. Thanks for responding.
