A balloon signalling system which includes a hollow flexible casing having a container section with an upper open end and a bottom closed end, and a cap for placement on the upper end of the container section. A hollow flexible flask having an opening is disposed in the container section. Disposed in the flask is a reactable material which when contacted by a certain solution, produces hydrogen gas. Also disposed in the flask is a cartridge which is breakable when bent, with the cartridge containing the certain solution. A string or other tether is held in the container section of the casing, with one end of the string being attached to the casing. Also included is an inflatable balloon dimensioned to fit in the cap when deflated and having a mouth through which gas may pass into and out of the balloon. Positioned in the mouth is a one-way valve for allowing hydrogen gas to enter the balloon and for preventing discharge of gas therefrom. A tube connects the opening of the flask to the valve to carry hydrogen gas from the flask to the balloon to inflate the balloon. The other end of the string is attached to the balloon.

A balloon signalling system comprising a hollow resilient casing having a container section with an upper open end and a bottom closed end, and a cap placeable on and removable from the upper end of the container section, a hollow resilient flask having an opening and removably disposed in the container section of the casing, a reactable material disposed in the flask, a breakable cartridge disposed in the flask with the reactable material and containing a solution which, when it contacts the reactable material, produces hydrogen gas, wherein said casing is bent until the cartridge breaks to release the solution, an inflatable balloon having an opening for receiving hydrogen gas to be inflated thereby, said balloon being collapsible to fit within the casing above the flask, a nozzle means disposed in the balloon opening for allowing hydrogen gas to enter and inflate the balloon, and for preventing the escape of hydrogen gas from the balloon, said nozzle including receiving means for releaseably receiving the end of a tube, a tube coupling the opening of the flask to the receiving means of the nozzle means for carrying to the balloon hydrogen gas produced in the flask, to thereby inflate the balloon and cause it to rise from the casing and pull the nozzle means off the tube, and tether means attached to the balloon or nozzle means for holding the balloon from rising above a certain altitude.
