When a retired chemist wrote in… we had to explore to his great questions. How does reverse osmosis actually work? Should you put aluminum foil in your dishwasher? Why do mixed powders mysteriously un-mix themselves? This episode is full of clever questions, surprising chemistry, and very strong contributions from listener Vince!

Question and Response #76

You asked… so we answered. What do carbon chains have to do with Greek words? How do MRIs make “3D pixels”? Is that pool smell actually chlorine? And wait… are birds blue, or is that just a trick of the light? This episode is a rapid-fire round of your questions, and the chemistry behind them.
