#041 Ok! So now that you know how teflon works (see last week's episode if you missed it), now it's time to discuss the equally important question: is it safe to use?? Are there any potential side-effects to using it? Can scratching teflon cause it to have an affect on our food, or even worse, on us? If there are potential dangers to teflon, is there any way to avoid them? Help! This week, Melissa and Jam delve into this topic, and tiptoe through the allegations to give you some things to consider when choosing you next pots and pans.   References from this episodeOrganic Chemistry, Edition 11 - SolomonIf nothing sticks to Teflon, how does it stick to pans? - Scientific AmericanDuPont Faces Class-Action Lawsuits Over Teflon - Reich, Chemical and Engineering NewsPerspective on Fluorocarbon Chemistry - David M.

Is it safe to use teflon pans?

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.

Why does hair turn grey when we age?

#030 Rebroadcast
Melissa and Jam continue to sniff out the chemistry of smell, focusing this week on bad smells. Why are we so good at smelling bad smells? Why do they haunt us at night? Why are some bad smells so strong and long lasting, while many great smells are subtle and temporary. What’s in a smell? "That which we call a rose by any other name would smell as sweet." I think that quote applies here right?
