A wrist mounted toy is described wherein a pressurized canister containing a string foam compound, or other pressurizable liquid with mid to low viscosity, is attached to a vessel containing a check valve. A geared-trigger mechanism allows for the user to expel the fluid at a pressure and rate dependent on the pressure he or she places on the lever. Additionally, the actions of removing and replacing the air and fluid canisters provide the user with a more interactive experience compared to a simple load and shoot toy. Many variations can be adapted to the toy to allow for a wide range of uses. The toy allows the user to enjoy a device which resembles the Marvel character's shooter more closely and discharge the fluid to quite a distance.

A dispensing canister apparatus for controlled release of a stored fluid includes first and second thermochromic clips for providing a visual indication of the ambient air temperature; a hose member surrounding a channel and having first and second open ends, and the first open end being connected to the canister such that the channel is in fluid flow communication with the inner cavity; a control on the canister for selectively actuating the flow of the stored fluid from the inner cavity into the channel and through a coupler member at the second open end of the hose member; and wherein storage of the first thermochromic clip in the first receptacle positions the fastening member such that it obstructs movement of the control for actuating the flow of the stored fluid.
