Episode Date
Why does orange juice taste bad after you brush your teeth?
1732
It's the lesson we've all had to learn the hard way. The pain our mouths feel when we take a treacherous swig of the post-brush poison. This week, Melissa and Jam delve into all of our childhoods to figure out the chemistry of this infamous mixture. Why does it taste so bad? Who's fault is it, the toothpaste or the orange juice? Also while we're at it, why is it called toothpaste? Nevermind, I'm not sure we'll be able to get to the bottom of that part.

How does soap kill COVID-19?
2065
Ok so we've known for awhile how soap works in a general use sense, like how it cleans dishes (see episode 1). But these weird times call for a deeper look at soap. How can it kill a virus? Or more importantly, how can it kill a little, wretched, mischievous virus like COVID-19? Like really, how? How is it that we can use soap to both get spaghetti sauce off a plate, and kill a dangerous virus? We're always told to wash our hands well, and that it's important, but if you think about it for a second, it's crazy that we put something on our hands, and rub them together under water, and then we're good to go. Right? Let's get into it.

How do thermoses keep coffee hot?
1853
That's right, we are sort of talking about coffee this week. Or rather, how to keep it hot. Nowadays we all have some version of a thermos for our coffee, tea, water, or what-have-you. Today Melissa and Jam try to get to the bottom of how those work. How do they keep things hot and cold? What's between the two layers (or whatever) and how is it so good at insulating? Is it a vacuum? Can someone please tell me what the heck is going on?

Why do bad smells smell bad?
1884
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?
Feb 13, 2020
How do we smell things?
2072
What's that smell? This week, Melissa and Jam explore the chemistry of smell. Now a lot of smell science has to do with our physiology and neurology. We'll talk some about that, but the chemistry has to do with the actual smells in the air. What are they? How do they get into the air? How can we detect them with our noses and brains? Why does rain have a smell, and why does it smell good? Let's find out.
