Abstract: The present invention includes a nozzle for creating and controlling geysers erupting from carbonated soda bottles. The present invention also includes methods of starting and controlling soda geyser fountains including remote triggering and chain reaction geysers. The nozzle of the invention is used for combining ordinary carbonated soda and small objects. The small objects are typically candies, such as MENTOS. The combination of soda and small objects creates a reaction that rapidly releases carbon dioxide causing tall, geyser-like fountains of soda. The nozzle includes a base section for securing to a bottle of soda, a pin and chamber section for holding small objects, and a nozzle orifice for controlling fluid flow.
