¿Qué es un escudo de agua?
Water shield is another term for hydro shield. It is a projection surfaces made of water for making laser graphics and effects visible. Water shields emerge water semicircular from the bottom upwards. They consist of a special 180° flat nozzle together with a very strong pump system. It is essential to have a permanent water source, therefore the nozzle may be placed in a lake or the like. Water shields are often used for rear projections and are able to disappear within seconds - an advantage over other kinds of screens.
