I remember as a child going to the Magic Kingdom and around noon or 1:00pm each day a massive amounts of balloons would be launched into the sky from Cinderellas castle. I loved that so much. I would watch them float away on a sunny day and most of the balloons would stay clustered together and could be seen for miles. Later i realized that the Disney Park stopped doing this because sea turtles in the oceans would mistake them for jellyfish and eat them and die. I fully understand why the balloons were no longer used. I was thinking, if rice paper or soy oil or corn oil etc. were used to make the balloons, or some other product that would degrade in water, then the balloons could be launched again. Also, the balloons sold to children in the parks could be made from the same material. Another concern is that some people are allergic to latex products made from rubber. This might cut down or eliminate this allergic reaction as well as be more friendly for the environment. These organic balloons could also be brightly colored just like latex balloons.
