A drawing tower produces a fine glass filament by drawing a glass preform. The tip of the preform is heated to melting temperature and then a strand of molten material is pulled downward.[1] Industrial drawing towers range in height from 30 to 45 meters. A drawing tower is used in the production of optical fiber, for example for fiber-optic communication cables. The preform is a multi-layered cylinder typically 20 cm in diameter, and 2 m long.[2]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
