It's one of life's most head-scratchy questions, and one of the most popular chemistry mysteries for youtubers. So let's get to the bottom of this crazy, shape-shifting substance, and finally find out why cornstarch and water do that thing!
Who's doing what to our salt? What's iodine, do we need it, why, and how do they get it in there? This week Melissa and Jam dive head first into figurative iodized salt dunes. Let's take a closer look at the chemistry of something so everyday, we hardly even think about it.
Happy New Years Eve! Let's all kiss 2020 a speedy (not speedy enough) goodbye and look at some beautiful exploding lights! And why not look at the chemistry in these things as well. How do fireworks work? How do they get up into the air? And most importantly, how do they explode in different colors and patterns? Let's find out! And thanks for being one of the great things about 2020, we love you guys!
Here's another bonus episode dedicated to teaching a specific chemistry experiment you can do at home. This month, we see what happens when we experiment with diapers, and the mysterious dust within them.
Happy holidays, we hope you have a wonderful season whatever you celebrate! We've got a holiday related episode for you: LEDs. Well I guess we use them all year round, but they get an extra spotlight this time of year. What are they? How do they work? How are they different from other lights? Let's find out!

This time of year, it's a common occurrence, something so common that we might not even wonder about it anymore. But really, why do we see our breath in the air when it's cold? We see steam from cooking things and boiling water, but our breath isn't that hot, so why do we see it? What does temperature have to do with it? Let's find out.
Well if you haven't experienced silver tarnish yourself, then you've almost certainly heard people complain about it. Can anything last? These sparkly treasures we collect and cherish, are they but temporary sparkles, doomed to a fate of tarnish? Or is there a way out? Also what is tarnish? Thankfully in this case, these philosophical questions actually have a chemistry explanation. So let's get into it.
You know what they say, everyone's experienced odors, and 99.99% of all odors smell. We have room sprays, candles, air fresheners, etc. But how can we absorb or eliminate bad smells? Can chemistry do it? How? Let's find out!
Here's another bonus episode dedicated to teaching a specific chemistry experiment you can do at home. This month, we see what happens when we cut up different colors of leaves, put them in alcohol, mash them up, and soak a coffee filter in them.
It's time to crack into one of life's great mysteries: eggs. So what happens when we cook them?! How do they go from clear goo to white jiggle? This is a question we received long ago, and with topics this serious, we don't yoke around. So we waiting until we could bring in an eggsperienced egg chef, Jason Cress, to figure out this topic with us. In Jam's opinion, Jason's insight on the topic of eggs just can't be beat. We know many of you guys may be busy with some (hopefully safe) version of Thanksgiving, but despite the holiday we couldn't pass on the chance to shell out another episode for you guys, especially for our friends around the world, who are just experiencing a regular ol' Thursday today.

In this month's bonus episode, Melissa and Jam respond to comments and questions about equilibrium, recycling on a large scale, why leaves fall off, sound effects, and Avatar: The Last Airbender.
Ok parents. It's time to explore the chemistry of something we rely on every hour of every day: diapers. What the heck is going on inside there? How do they absorb SO much? Is it magic? Well, settle in and get ready to soak up some chemistry, let's get to the bottom of this mystery. Let's hope it doesn't get messy.
There's this stuff, you've probably heard of it, that you can put on 10-20 specific places on your body, and it stays there, and it can be different colors. That's right, it's nail polish! What is nail polish? It sticks, but it's obviously not just glue right? It's colorful, but it's clearly not just paint right? What chemistry is going on in nail polish? How is it strong and long lasting? How does it dry so quickly? So many questions, let's get into it! PS. Some of you fellas may be thinking this won't interest you, but we'll bet the chemistry is more interesting than you'd expect!
This week we issue a correction, joining other science publications issuing the same correction. That's kind of an obvious answer to the question of "Is science always right?" So in this episode we explore that question, as well as what happens when science isn't right. And why that's NOT a bad thing.
Guess what time of year it is. It's spooky time! One thing we see a lot of during this time of year, is things that glow. And you better believe that's chemistry. So how do glowsticks glow? How does bending the glowsticks start that process? What's mixing with what, and seriously how the heck does it glow? Let's find out.
Here's another bonus episode dedicated to teaching a specific chemistry experiment you can do at home. This month, we see what happens when we blend up red cabbage and water, and mix it with six different substances.
This week we take a teeny tiny step into the vast, intimidating sea of essential oils. Not to worry, we're sticking to the chemistry. And we're exploring one of the smelliest, purply-est ones.
