I'm organising a funeral, and one of the ideas that has come up is for people to write memories on a balloon and let them go. However, I've also heard that they often end up in trees etc and are terrible for the environment.
Is there such a thing as environmentally safe balloons? Other suggestions are also welcome.
Another thing that I'm not seeing people mention is helium balloons wandering to places like power substations and/or power lines, causing outages or even fires/explosions depending.
I liked what someone else said about writing thoughts or stories and having them read anonymously.
