Balloons are made of natural latex. Latex is the milky sap of the rubber tree which grows in tropical regions of the world such as East India, Brazil, Malaysia and Guatemala. Each tree lives for about 35 years and produces enough sap for approximately three balloons daily. The continuing demand for latex balloons ensures the survival of the rubber tree and provides an economic incentive for planting (instead of cutting down) these trees.
Helium is an inert natural gas. When a helium balloon is released into the atmosphere, it will rise to approximately 8,500 meters. At this altitude the helium expands and the latex balloon becomes brittle, causing the balloon to shatter into tiny pieces before returning to earth. For more information on balloons and the environment check out the BASA website.
CAN I RELEASE BALLOONS INTO THE AIR?
By law it is illegal to release 20 or more gas-inflated balloons at or about the same time. If you are not sure, please contact the Central Coast Council for more information.
The balloons should not have any attachments. On-the-spot fines can be given and penalties are much higher if over 100 balloons are released. This ruling comes under the Protection of the Environment Operations Act 1997- Amendment (Balloons) Act 2000.
