A rocket net is a kind of animal trap used to trap a large number of live animals, usually birds. It consists of an accordion folded rectangular net with one edge attached to the ground. The corners of the opposite edge at the top of the folded heap are attached to heavy tubes with one closed end. These tubes are placed over stakes set at an angle. The stakes have a hollow in the end where an electrically activated shell is placed. When the shells are activated the heavy tubes shoot up at an angle and the net is spread across an area that was previously baited to attract the desired animals.
Rocket nets, as well as the very similar cannon nets, are used in conservation programs where a large number of live animals need to be captured for analysis, veterinary care or relocation.

Famous quotes containing the words rocket and/or net:
“A rocket is a reed that thinks brilliantly.”
—José Bergamín (1895–1983)
“A culture may be conceived as a network of beliefs and purposes in which any string in the net pulls and is pulled by the others, thus perpetually changing the configuration of the whole. If the cultural element called morals takes on a new shape, we must ask what other strings have pulled it out of line. It cannot be one solitary string, nor even the strings nearby, for the network is three-dimensional at least.”
—Jacques Barzun (b. 1907)
