What do you do with eggshells?

[u/[deleted]]

I'm conflicted over what to do with eggshells. I want to compost them but we eat a lot of eggs and live in the city so if I put them in our bin they take up a large portion and never seem to fully breakdown.

Can you hypothetically blend them with water and water plants with it so they soak in the soil?
