Hi,

There's a whole area of practical experience that separates things on
whether they float or not - bad eggs float good eggs sink.

This is really weighing things, and it is possible to separate good seed
from bad by weighing each seed (given patience and a sensitive enough
scale). The good ones are the heaviest.

So seed that sinks is likely to be the most viable.

But some seed even when viable is not going to sink, some seed, e.g.
coconuts, has evolved to float when viable.
