I found an old open packet of these, who knows how long for. Popped them in water and some of them sink. Is this actually a thing or a myth? I don’t want to waste them.
I have soaked seed before, some sinks and some floats, but most seem to germinate. Soaking is supposed to help soften the seedcase to make it easier to break open.
I imagine very old seed will heave their kernels shrivelled up and replaced with air, so they float So there probably some truth in it

Knowledge is knowing that a tomato is a fruit. Wisdom is not putting it in a fruit salad.
When I’ve used old sweet pea seeds I sprout them before I sow them. I wrap the seeds in a square of kitchen paper, moisten it then pop the parcel into a small plastic box with a lid. Examine every couple of days. As soon as you see the tiny root/shoot emerge pot them up as normal. Saves wasting compost on unviable seed.

I never bother soaking them anyway.

I've known them take 2 weeks or more to appear in cool weather

Quicker than that means they've had too much heat, which isn't great for them.
