Tubing for BalloonSats
Link lines are the cords that tie one or more BalloonSats to a near spacecraft. So they don't tear a Styrofoam BalloonSat apart, there must be a race way attached to the BalloonSat for the lines to run through. Some groups have used flexible vinyl tubing and others ink pens with the guts removed. I prefer to use styrene plastic tubes. They come in a variety of sizes and are available at many hobby stores that sell airplanes, cars, models, and rockets. A 1/4" diameter tube seems to be ideal. Best of all, the tubes are very long and can be cut to the proper length. That way your BalloonSat dictates its proper size, not the tubes you have on hand.
