| Abstract: |
A method and apparatus is disclosed for creating artificial rain. The apparatus includes a substantially planar collection sheet having a plurality of pointed teeth along its lower edge. A water tank supplies water under pressure to an overhead manifold which feeds water to a plurality of spray nozzles adapted to spray a horizontal fan of water onto the collection sheet. As the water collects on the pointed teeth, it eventually falls off in droplet form when the volume and weight of the water overcomes its surface tension. An overspray sheet also having a plurality of pointed teeth may be positioned in spaced, parallel relation to the collection sheet to collect any overspray and convert it to drops of artificial rain. A control system regulates water pressure in the apparatus during use conditions. When the apparatus is deactivated, water is recycled in the tank while maintaining a balanced head pressure in the apparatus so that activation and deactivation takes only a few seconds.

I claim:
1. An apparatus for creating artificial rain, comprising:
- (a) a collection sheet having droplet forming means along the lower edge thereof for creating artificial rain drops from liquid applied to the sheet; and
- (b) means for applying liquid onto the sheet comprising a plurality of spray nozzles adapted to spray a relatively flat, wide fan of liquid under pressure which forms a thin and evenly distributed film of liquid on the collection sheet, whereby substantially all of the liquid applied to the sheet is formed by the droplet forming means into drops that fall from the sheet.
