FIELD OF THE INVENTION 
   Current application is related with a toy balloon saber, especially related with a toy balloon saber equipped with a lightening means that can be inflated by an air pump and contracted by an air outlet. 
   BACKGROUND OF THE INVENTION 
   ‘Star Wars’ is a legend in movie history of scientific fiction field. Many kind of props and characters are created for the movie. Copy of the props and miniatures of the characters were great success in toy market. Passion for them sustains even after the ‘Star Wars’ series is ended. Among them the most ‘want-to-have’ item for the kids and young men is the ‘Light Saber.’ Most fascinating part of the ‘Light Saber’ is that the light blade disappears when it is not used. That is totally new concept for a sword or saber. Realization of the real ‘Light Saber’ is impossible yet though the progress in laser technology enabled a laser gun to shoot down a missile and an energy shield on a restricted area. Meanwhile, many kind of toys are introduced in the market that insists a mimic of the ‘Light Saber.’ One of them is a fluorescent lamp attached on a handle that is a battery case. But, that is use-less as a toy because it is dangerous for the glass bulb that constitutes the blade body. It is purpose of the current invention to provide a safe toy ‘Light Saber’ that contracted and expanded safely and emits light when in use.

   SUMMARY OF THE INVENTION 
   ‘Star Wars’ is a legend in movie history of scientific fiction field. Many kind of props and characters are created for the movie. Copy of the props and miniatures of the characters were great success in toy market. Among them the most ‘want-to-have’ item for the kids and young men is the ‘Light Saber.’ Most fascinating part of the ‘Light Saber’ is that the light blade disappears when it is not used. That is totally new concept for a sword or saber. Realization of the real ‘Light Saber’ is impossible yet. It is purpose of the current invention to provide a safe toy ‘Light Saber’ that contracted and expanded safely and emits light when in use. A toy light saber, equipped with a lightening means, according to the current application is comprised of a blade part that is comprised of an elastic plastic balloon, a handle part that is comprised of a hand pump, and a flash light that is installed between the blade part and the handle part. The balloon blade is in a contracted state when not in use. When a user want to use the toy light saber, air is pumped into the balloon to tighten the balloon and make it stiff. The flash light is turned on when the saber is used. The light from the flash illuminates the balloon from inside and gives an impression of a light saber. Air is released from the balloon by disengaging a flip clamp that is used to hold the balloon. The balloon blade is stored inside of a flash light head after air is released and the balloon is contracted. Another embodiment of the current application is a toy balloon that does not have light source there within. Only hand air pump and balloon blade are connected.
