Chemistry For Your Life
A podcast that helps you understand the fascinating chemistry hidden in your everyday life. Have you ever wondered why onions make you cry? Or how soap gets your hands clean? What really is margarine, or why do trees change colors in the fall? Melissa is a chemist, and to answer these questions she started a podcast, called Chemistry for your life! In each episode Melissa explains the chemistry behind one of life’s mysteries to Jam, who is definitely not a chemist, but she explains it in a way that is easy to understand, and totally fascinating. If you’re someone who loves learning new things, or who wonders about the way the world works, then give us a listen.
