Does any one out there know of a material that can be shaped into a slightly larger than pingpong ball sized hollow ball that will float? It would also need to be biodegradable and/or dissintergrate after about 15 minutes of being immersed in room temperture water?
Can any one help?
Thank you for your responses.
