A self-inflatable balloon has a communication discernible on its surface and has its mouth opening pneumatically sealed to a funnel through which air is selectively directed upon actuation of a triggering event. Audible communication may also be actuated by the same or a different triggering event.

A self-inflatable balloon has a communication discernible on its surface and has its mouth opening pneumatically sealed to a funnel through which air is selectively directed upon actuation of a triggering event. Audible communication may also be actuated by the same or a different triggering event. A method of communicating comprises a message which becomes cognizable upon inflation of a message carrying device.
