If you need a long pole, you’ll often have to lash together two limbs or saplings to get the right length. This is the case when making a dome framework for wigwam-style shelters, for example. If cordage is in short supply, using an energy shot bottle (like a 5-Hour Energy or similar product) from your trash may be the solution. After slicing off the top and bottom of the bottle, a very strong cylindrical tube remains. You can use this tube as a collar for connecting the ends of two limbs. Taper the ends of the limbs so they slide into the tube opposite each other and form a snug fit when wedged together. This collar will hold them surprisingly well and will not stretch with moisture, as many lashings do. If the collar is a bit loose, heat it over coals or a flame and it will shrink and tighten the fit.
