Seeds
 

The message
from Hussein M. contains these words:

Freezing them will, to all intents and purposes, make them stay
viable indefinitely . (For most seeds I believe).

No it won't, especially with plant seeds which originated from warmer
climates.

Isn't it goldfish which can simply swim out of a thawing block of
ice?

No. Freezing your goldfish in solid ice will kill them.
