The video explains osmosis through a story about Nemo, a saltwater fish that dies in freshwater due to osmosis. Osmosis is the movement of solvent molecules through a semipermeable membrane. The video describes forward osmosis, pressure-enhanced osmosis, and reverse osmosis, using a U-tube example to illustrate osmotic pressure. It concludes with a call to action for viewers to engage with the content and download an educational app.
