In case the need should arise for an improvised and silent weapon:
In the class that I took, the blowgun was copper pipe and the darts were women's plastic necklace beads, each with a lenth of stiff wire stuck through it and sharpened. The longer the pipe, the more accurate the shootin, and the more the distance. If the dart is just the right size, it will increase the range and speed.
To coat the tip of the dart, our teacher suggested to soak the tobacco from a pack of cigarettes (or you could skip the paper and buy rollin tobacco) in water for a few days until the water dries out, then put the remainin goo on the tip of the dart. Viet Cong used to put feces on the tips of their sharpened bamboo booby traps, which became deadly after a while.
Some of the foes' infiltrators may have gotten laws to be passed bannin the possession of blowguns in your state. We therefore get together those laws to be repealed. That is one of the benefits of bein a member of Family Survivors, we can have collective might to get the legislation that we like!
In this one the toothpick might be more for practice, and you might want to use wire or a wire nail for serious purposes:
