Bamboo, as well as niu, coconut, is one of the most useful and practical plants for humankind, providing water storage, food, raw materials for household and garden use, musical instruments and more.
Bamboo wood has silica in its cell walls and is hard, straight, strong, flexible, light and easily split.
Split bamboo can be made into mats, hats, screens, baskets, fans, umbrellas, brushes, paper, ropes, roofing tiles, wall mats, or as a part of the sleds of old Hawai'i, called holua.
The stem of bamboo has been carbonized for use as electric lamp filaments, in goldsmithery, and tabashir, a fine powder used as a chemical catalyst.
