FLOAT Installations uses only natural latex balloons, harvested from rubber trees substainably grown in Africa and manufactured in Texas (Janice has visited the plant - it is amazing to see their production!).
These latex balloons are an organic material that biodegrade at the rate of a leaf.
More importantly, most sculptures are air filled, helium is rarely used, making it much less likely they can "escape". In both cases, Janices' top priority is maintaining the sculptures integrity so that no balloons are released or left behind in the environment.
FLOAT Installations will NEVER do a balloon release - so don't ask!
Aging balloons are either recycled into new sculptures or composted and popped balloons are saved for other art projects, including jewelry and weird but beautiful weaving experiments.
