Sea Worms. The sea worms are a large and varied group of animals belonging to a group called annelida. They are segmented worms, and all bear at least some resemblance to the common earthworm. In the ocean, however, the worms have evolved many different appearances. One of the more interesting varieties is the tube worms. These animals form a hard-shelled tube that provides them protection.
Earthbag building is a low-tech solution to making foundations (or entire buildings) using basic materials and simple tools. Drawing on the age-old technique of rammed earth building, earthbag uses woven sack material to provide a ready-made, leave-in-place formwork for containing rammed earth mixtures.
An airbag is a type of vehicle safety device and is an occupant restraint system. The airbag module is designed to inflate extremely rapidly then quickly deflate during a collision or impact with a surface or a rapid sudden deceleration. It consists of the airbag cushion, a flexible fabric bag, inflation module and impact sensor. The purpose of the airbag is to provide the occupants a soft cushioning and restraint during a crash event to prevent any impact or impact-caused injuries between the flailing occupant and the interior of the vehicle.
