When the natives of the rainforest are in need of food, they enlist the help of various poisonous frogs to supply them with killing power. They will keep a bamboo “quiver” like the one shown above filled with darts. They need to keep them secure and out of the way to prevent accidentally pricking themselves. They have hunted this way for thousands of years successfully. Although some of the poisons used in these hunting methods are derived from a plant known as curare, some species of dart frogs are still used.
The odd looking item in the second image (below) is a dried out gourd, which is filled with silk cotton from kapok trees. This cotton is used as an air seal as it is wrapped around the rear end of the dart. Essentially this gourd is a convenient cotton dispenser.
The Darts are made from lengths of palm leaves. The stiff mid rib in the center of the palm is needed. One end of these is sharpened and placed on the skin of the poisonous frog or a species of plant to collect the poison. These extremely powerful nerve and muscle toxins are lethal to any animal.
Shown in the image below are some of the actual darts from a tribe native to the amazon rainforest.
Finally, the image below is the actual blowgun of an Amazon rainforest native. As you can see this one has been around a few seasons. This particular weapon was on display at Midland center for the arts in MI. The length of this blowgun is an astonishing 7 feet or more. These are carved from wood with a bamboo tube in the center as the barrel.
This video below is showing a native rainforest tribesman using a blowgun very similar to the one shown here.
