Definition
A fountain is a ground device that burns without projecting anything: a cardboard or plastic tube, choked at its outlet, whose composition burns away producing a spray of silver, gold or coloured sparks. Height ranges from 1 to 8 m and duration from 20 seconds to over a minute; display models reach 10 m. The sparks come from titanium, aluminium or iron filings, sometimes mixed with crackling or coloured stars. It is planted upright for a column, angled in crossing pairs for curtains, or hung upside down for a waterfall. Almost silent, the fountain is fired close to the audience in categories F1 to F3, and in T1 and T2 for low-fallout stage versions.
In practice, for the display company
Fountains often open a show or underline a façade, and their duration serves as a carpet beneath the first shells. PyroDesk keeps height and duration on the product sheet so the timeline shows the true length of the effect; PyroSimulator renders the spark spray with its sound, and the short safety distance is carried into the site plan.
