How it works
A powerful pump pushes water through a wide nozzle that spreads it into a thin, fan-shaped sheet of spray, which can be tens of metres wide. Projectors or lasers aimed at the spray light up the droplets, so images seem to hang in the air.
Water screens are usually part of a larger show, with a musical fountain, lasers and flame effects running on the same timeline. Some are built into lakes and pools for nightly shows, others float on a pontoon for a single event.
Good to know
- It only works properly after dark, so it suits evening and night shows.
- Wind breaks up the spray and blows mist onto the audience, so the screen faces away from the main wind direction where possible.
- Content looks best with bold shapes and dark backgrounds, because fine detail and text get lost in the spray.
- The screen needs a body of water or a tank to draw from and return to.
