A family that I was working with told me about a really interesting item that can be used to send remains (cremations) out to sea. It is a floating pillow. Who knew!?
These urns are sturdy, easy to use and 100% biodegradable. They are water friendly for ocean, lake or wide river. They can be placed directly into water and will slip under the water within minutes. There are lots of options, check them out here.
