Perhaps multiple bottles. I was the one (oldest male) selected to send my Aunt on her way. The ashes were actually sort of heavy and would have needed a 2 liter bottle as someone else suggested. Not sure a bottle full of ashes would have floated.
We didn't use a bottle(s), but did send her ashes out to sea. The funeral home had my Aunt packed in a plastic bag. We took her with us to Ocean City MD. As nobody wanted to do this by boat
, it took a while to find a spot along the beach that didn't have people. I waded into the surf and tried dumping her out. Some of her ashes came out and the wind
blew them all over me. Try as I might, I could not get all of her out of the bag.
Maybe it was divine intervention, but as I slowly walked farther out, a breaker hit me hard and when the water
receded, I was soaked, but the ashes were gone and the bag was completely empty. Mission accomplished. I was still laughing about it when I returned to my family
at the top of the dune path (my Mom was in a wheel
chair). Of course they were all still crying, so I had to bite my lip to get the smile off my face. But into the Atlantic she went. She arrived in America by boat
, it was fitting she return to the waters she once crossed.
