Why do leaves change color in the fall?

It's Fall! You know why they call Fall Fall? Well because the leaves fall. But before that, the leaves change color. Why do they do that? How? Is there any sort of function to it? Do the different colors mean anything? Let's dive into this overdue, colorful topic.

What's the future of recycling?

Part 3 of 3 on plastic! This week we look to the future. Is there hope to overcome our piles of plastic? What new ways of recycling are coming down the pike? What are those sneaky chemists up to? Can we make better kinds of plastic, or better ways to reuse it? Let's find out. And let's try to stay positive.

Is plastic really recyclable?

This is part 2 of 3 on plastic, so check out last week's episode if you haven't yet! This week, Melissa and Jam dive into one of the weightiest questions of our day. Is plastic even really recyclable? If so, how is it done? Is it really better than just making new plastic? Is it worth all the trouble of rinsing and sorting our recycling? Is recycling effective enough to lead us toward a cleaner future? Let's try our best to find out.

Chemistry at Home: Slime

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 combine glue, water, and borax!

What is plastic?

Think about it for a second, plastic is everywhere. What plastic things are around you right now? What plastic things do you use everyday? This week, Melissa and Jam dive right into the proverbial (and sort of literal) ball pit. What even is plastic? What is it made of? How is it made? How are there so many different kinds? Let's find out.

Bonus: Why doesn’t superglue harden in the tube? (and other questions)

In this month's bonus episode, Melissa and Jam respond to comments and questions about gasoline, super glue, smells, books, and a continuation of last month's movie discussion!

How does super glue glue things?

Be honest. Have you ever glued yourself with super glue? Everyone should accidentally make that mistake at least once, so you can literally feel the impressive stickiness of super glue. Well today, you can learn about the chemistry within super glue, without putting any fingers or other body parts at risk! Let's do this.

Why do we use fluoride on our teeth?

Chances are you've heard the word "fluoride" said in reference to your teeth. At the dentists office, on your bottle of mouthwash, maybe you've heard it's in tap water? But what is it, what's so special about it, and how does it help our teeth? Does it make them whiter, stronger, or what? Let's find out.

How does caffeine make you not sleepy?

Ok so, caffeine. Some of us live on the stuff, and others of us want nothing to do with it. There's a lot of things caffeine can do to our bodies, but of course the number one question, is how does it keep the sleepiness away? Let's get into it. And we may find out a few other things caffeine does along the way.

Chemistry at Home: Density

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 combine honey, corn syrup, dish soap, water, oil, and alcohol.

What makes fruit ripen?

Fruit. You eat it too early? It tastes bland and tart. You eat it too late? And it's rotten. You eat it when it's ripe? It's perfect, sweet, and juicy. What makes fruit ripen? How is it that supermarkets and suppliers can control when fruit ripens, or keep it from ripening too early? What's telling what to ripen when? And how? Let's talk about it.

Bonus: Do mosquitos care about blood-type? (and other questions)

In this month's bonus episode, Melissa and Jam respond to comments and questions about mosquito repellents, mosquitos and blood type, mosquito saliva, organic chemistry, and some of our favorite movies!

What's up with alcohol(s)?

So we all know what we think of when we hear the word "alcohol," but what if that's not really the whole picture? There's actually many kinds of alcohol, most of which we cannot drink. So what's up with all those alcohols? What makes them different? What makes them similar enough to all be called alcohol? Let's find out.

What IS fire? (and what happened in Beirut?)

Seriously. What is fire? This week Melissa and Jam hop out of the frying pan. What are those warm orange wisps? We all sort of know what fire is but also, do we? It's hot, it can be good, it can be bad. But why does it look like that? And what really IS it? Let's try to find out

What makes honey crystallize?

Ever notice that honey crystalizes? Isn't that like super weird? Why does it do that? This week, Melissa and Jam risk getting stuck in this question.

What is the future of mosquito repellents?

This week, Melissa and Jam close out the mosquitos series with part 4 (If you missed the previous three, go check them out). What does the future look like for humans and mosquitos? Can we finally achieve peace? What are scientists working on, ways to make us invisible to mosquitos, or ways to kill them all? Or can things even get better at all? Let's find out. Scientists, we're counting on you, don't let us down.

Chemistry at Home: Milk and Soap

Our third bonus episode dedicated to teaching a specific chemistry experiment you can do at home. This month, we see what happens when we combine milk, food coloring, and dish soap. Let's do chemistry together!

What even is DEET?

This week, Melissa and Jam continue to part 3 on the topic of mosquitos (If you missed the previous two, go check them out). What is DEET? What part does it play in repelling mosquitos? How do repellants repel mosquitos in the first place? Is it just straight witchcraft? Let's do it.

Bonus: Is rain just like sweat for the earth? (and other questions)

In this month's bonus episode, Melissa and Jam respond to comments and questions about carbonation, color-changing dyes, spiciness, rain, babies, merch, and more!

Do mosquitos bite some people more than others?

This week, Melissa and Jam continue the topic of mosquitos (If you missed last week's, listen to it first). It's time to answer the age-old, every-summer question. Why do some people get bitten by mosquitos more than other people? Or maybe, does this really happen in the first place? If so why? What factors do mosquitos look for, compare, and choose by? Let's get to the bottom of this.

Why do mosquitos bite people?

This week, Melissa and Jam begin a multi-faceted topic: mosquitos. Now of course mosquitos are insects, so studying them would mostly fall into biology. But there's a lot of chemistry here too. The first question, why do mosquitos bite humans at all? How do they find us, and why do they want to bother us? And perhaps more importantly, how is it related to chemistry? Let's find out.

How does sweat cool us down?

This week, Melissa and Jam once again look under the armpits of society, this time to explore sweat. Is it cool? Well does it keep us cool? How? At what cost? Is there more to sweat than meets the eye? Can you drink it? Grab your sweat bands and let's hit the track Paulie Bleeker.

Chemistry at home: Chromatography

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 combine markers, coffee filters, and water. Let's do chemistry!

What is a calorie?

This week, Melissa and Jam question the whole system of food. Or rather, the way we calculate food: calories. What are they? Where'd the come from? How are they calculated? Is it a good system for measuring food? What does it actually measure? Can we calculate calories in food at home? Let's dig in.
