In reply to StockportAl:
Small rock-throwing children can be addressed quite safely and from a distance:
To make a blowpipe, start with a long, narrow tube, traditionally made from bamboo or other lightweight, sturdy wood. The tube is carefully hollowed out and smoothed to ensure air flows freely through it.
To craft poison-tipped darts, Amazonian tribes often use the secretions from certain toxic frogs, such as the Phyllobates species. These frogs excrete potent toxins on their skin, which is collected and applied to the tips of small, thin darts made from wood, bone, or other materials. The darts are then fired from the blowpipe, with the poison immobilizing or killing your target, making them effective tools for either leader of belayer under attack.
