• Cigarette smoke. It diffuses into air and spreads through the room. 
• A sugar cube in a glass of water that is not stirred will dissolve slowly and the sugar molecules will distribute over the water by diffusion. 
• The smell of cookies diffuses through the house as they bake. 
• Tea leaf pigments diffuse through the tea bag to give the water its colour and taste of tea. 
• Air freshner / deodorant molecules diffuse into the air when put on. So we can smell it. 
• If the cooking gas is leaked, it spreads all over the house through diffusion.
