A toy is disclosed for producing a simulated eruption. The toy comprises a container having a first chamber for holding a predetermined quantity of a first reagent and a second chamber for holding a predetermined quantity of a second reagent. The second chamber communicates with an upstanding convergent nozzle terminating at its upper end in an orifice opening to the exterior of the container. When the sidewalls defining the first chamber are squeezed, a portion of the first reagent held therein is forced through a connecting tube into the second chamber, where the first regent reacts with the second reagent to produce gaseous products. The elevated pressure thereby created within the second chamber causes the reagent mixture to be ejected from the nozzle orifice at high velocity. The toy may additionally comprise a simulated volcano landscape having a eruption tube depending from the volcano crater which receives at its lower end the tip of the nozzle. A simulated eruption from the volcano\s crater is thus produced.

A toy for creating a simulated eruption comprising: a dual-chambered container comprising: a first chamber for holding a predetermined quantity of a first reagent, said first chamber including means for adding said first reagent thereto and further including a removable closure for closing said first chamber to the atmosphere, said first chamber having walls of flexible construction; a second chamber for holding a predetermined quantity of a second reagent, said second chamber having its lowermost portion disposed above the uppermost portion of said first chamber; an upstanding nozzle removably secured to and communicating with said second chamber and terminating at its upper end in an orifice opening to the exterior of said container; an elongated connector tube extending between said first chamber and said second chamber, said connector tube opening at its bottom end to the lower portion of said first chamber and at its upper end to the upper portion of said send chamber, said connector tube permitting the flow therethrough of said first reagent from said first chamber to said second chamber when said walls of said first chamber are compressed, and; a simulated landscape disposed above said container, said landscape including at least one downwardly directed hollow channel opening at its upper end to the upper surface of said simulate landscape, said channel interiorly receiving at its lower end the upper portion of said nozzle.
