A "plinking" weapon for the UK

[Steve]

As a youth I used to make blowpipe darts, they are easy to make and surprisingly accurate. The method is not easy to describe, it involves cutting a strip of shiny type paper from a magazine, about 2.5" wide and the length of the page. Hold the end and twist it so that the paper forms a cone, keep twisting and pulling the cone until it starts to get long and pointed. The angle of the remaining strip will get closer to 90 degrees to the dart body as you get towards the pointed end, when it is nearly 90 degrees tear it off about 1" from the dart, lick it and wrap it around the dart, plenty of spit will hold it in place. When dry you can cut off the point to leave a hole in the end and drop a nail in from the open end, with a little PVA on it. You can trim the dart to length so it fits your blowpipe, something about 20mm diameter will work well, and either leave it as it is or apply a coat of varnish to toughen it up.

A dart like this will easily pierce a metal dustbin and they fly very straight. Try to use a blowpipe of decent size, the thin walled tubing commonly used as hanger rails in wardrobes is good.
