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.
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.
Do you like apples? Ever wonder why they turn brown when you cut them? This week, Melissa and Jam explore this very question. What's going on in these apples? Where does the brown come from? Is it a good or bad thing? Does it taste different? Is the brown actually apple tears from the pain of being cut?
In his month's bonus episode, Melissa and Jam respond to comments and questions about methane, bad smells, bleach, computers seeing colors, crystal formation, and more!.
This week, Melissa and Jam explore the oldest question in the book. But we're not going to answer it. Just kidding. Why the HECK is the sky blue? And also why are there times that it isn't? Sunrise? Sunset? Nightime? Sky, what are your mysteries? Tell us your secrets. Hide not your face from me.
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?
This week, Melissa and Jam investigate reusable hand warmers. How do they get hot? Where does the heat even come from? How do reusable ones even work? Is it real? How can heat just come out of nowhere like that?
How does bleach bleach stuff? Oh and also, what even is color? This week Melissa and Jam investigate these questions. What's the molecular makeup of color and then how does bleach alter that? How does bleach have enough power to ruin that hoodie you just bought? How could you have been foolish enough to handle bleach while wearing your new hoodie?
In his month's bonus episode, Melissa and Jam respond to comments and questions about cold/cool, water temperature's effect on boats, vapor pressure, smells, hair, and how this podcast even got started.
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?
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.
This week, Melissa and Jam travel even further down the rabbit hole of hair chemistry. How does our hair get damaged? How do we curl, straighten, and perm our hair? What's going on there at the molecular level? Let's find out!
This week, Melissa and Jam dive into the chemistry of something that may not seem like chemistry at first: hair. Curly hair to be specific. What makes hair curl? Also what is hair in the first place? Why can hair be so radically different? Alright curly girls, curly guys, and curly folks, let's find out.
In his month's bonus episode, Melissa and Jam respond to comments and questions about how to grow crystals, details about snowflake formation, a little tiny bit of discussion about blackholes, and more!
This week, Melissa and Jam discuss part of an often requested topic: carbonation. Does it have a taste? Like why does carbonated water taste different than flat water? And what is carbonation in the first place? Does it give you unusually long life? How is it so refreshing? We answer some of those questions.
This week, Melissa, Jam, and very special guest Renee Collini (Melissa's sister) delve into the important topic of sea-level rise. What causes it to rise? What affect will it have on the world? How should we feel about it? Is there anything we can do as regular people?
This week, Melissa and Jam explore three very different, but related, light phenomena. We'll discuss situations when light can be bent, slowed down, and even broken. It's gonna be lit.
