7 years ago i buried my pet fish in the back yard in a little plastic container filled with water. What state do you think its in today?

@Jackaloftheazuresand the kind we use for food. Like a tubberware container with the seal lid.

@Eternity yeah, that would probably stand up to climate variations unless the water froze and stretched it until it broke a small hole. Of course there are also microbes that would have already been on your fish and with decay would create gas which could break the seal and further exposing it to reclamation.
