How does osmosis work in real life?

Could you please explain, in a straightforward manner, how the concept of osmosis actually operates in our daily lives? I'm curious to understand the practical applications of this scientific phenomenon and how it might relate to our surroundings, whether it's in nature or in technology. Can you give a few examples to illustrate your points? I'm particularly interested in how osmosis might be used or observed in different scenarios, both simple and complex.
