Sometimes I open a room-temperature bottle of red wine and put in a valved spout. On operating the valve the next day, at the same temperature, the noise I hear suggests that the air in the bottle was at a lower pressure than that outside. Why should this be?
I spend a lot of time outdoors and wearing fleece jackets seemed a good use of recycled plastic. I now learn that every time I wash them, I pollute the oceans with microscopic fibres. If they go to landfill, they will presumably stay there for hundreds of years and may leach toxins into the environment. Should I continue to wear them? What is the best way of disposing of them?
