Just for a little fun I did a little experiment today and made a little blowpipe and dart from Bamboo. I cleared the pith from the center of the bamboo using a 3mm brass rod,then smoothed the ends with sand paper. At the end I was going to use to blow through I wrapped it with a leather strip held in place with pine resin and at the other end I wrapped some jute twine and then also coated that with resin. The dart was made from a split piece of bamboo which I the split a fine length no thicker that 2mm in diameter,I sanded one end into a fine point and then wrapped some cotton wool around the other end. I then tested the blow gun out by firing it at the ironing board which hangs from the back of a cupboard door,don't tell the Wife It stuck in first time. I decided to put a picture on the ironing board and see how consistent I was from about 15 feet,not to bad really as you will see from the holes in the picture. The blow gun is only 12" long and fires really well up to 25ft,if I had made it longer Im sure it would have been accurate at a much longer distance. So all I need now it a poison dart frog and im in business,only kidding ,but it just goes to show how easy it is to make a blowgun and what a versatile plant bamboo really is.
