Don't Let go... Why?
Even though all the latex balloon we use are certified biodegradable the ribbon attach to them is not. Also, you need to understand that it is a process that take times depending on the make, colour, weather exposure and many other factors.
Mylar and foil balloons are made of different material and are not biodegradable, there are ways we re-use them and recycle them but at the end everything that goes up must come down eventually and this poses real danger to wildlife and even humans. so please DONT LET GO!
Balloons could get caught on powerlines or animals, trees. This is the main reason why we do not support balloon releases. after you enjoyed your balloons make sure to pop them and place them in the trash.
We also use water weight to avoid the use of plastic or concrete weights. make sure you drain the water carefully in the sink and dispose of the balloon and ribbon in the trash
