What is that iconic smell? The smell that screams spring and summer? The smell so distinct, and yet so mysterious. Why does freshly cut grass have that smell? Why is it so strong? Could it be chemistry?
Now it's time to dive into one of chocolate's biggest mysteries. Which, depending on where you live, has been something you've wondered for a long time, or you've never even known it was a mystery. Why is chocolate different in the United States? Is it on purpose? If so why? Is there a benefit? Is it because companies in the U.S. are cheapskates? Or is it because they're innovative? 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 combine chocolate and gum. Yep, you read that right. And yes, it's a little gross.
You know how when you were a kid, you'd sometimes find some old, forgotten halloween chocolate? But the chocolate would look a little white, and if you risked eating it, it would taste weird? Well we're not ashamed to say we've experienced this even as adults, but this time we're taking a close look at this strange mystery. Why does it happen? How long does it take? Why does it affect both the look and the taste? Let's find out.
In this month's bonus episode, Melissa and Jam respond to comments and questions about leaves, labs you can do at home, electrophilic aromatic substitution reactions, pancakes, easter candy, and more!
Well you've probably never heard of chocolate, and you've almost certainly never eaten it. But if you had you might wonder, what the heck is this? How do they make it? And why does it taste so gosh darn good?
It's of the most puzzling (and heartbreaking) mysteries. Why does cilantro taste so good to some of us, but taste so bad to others of us? Is it in our heads? Or is there a chemical explanation for it? If so, what is it? And can it be fixed?
This question comes from a word-working listener of ours. Ebonized wood is a process that turns wood black... without burning it! But how? What's the chemistry behind it? Is it cool? Yes, yes it is cool.
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 crayons, paper, and water.
Remember those markers that would *magically* change colors when you marked over them with the right marker? Well while it seems very magical, it's actually chemistry! What a surprise. So how does it work? What's going on at the molecular level? Is it still as cool as it seemed when we were kids? Yes.
In this month's bonus episode, Melissa and Jam respond to comments and questions about gunpowder, our wellbeing, food colors, hair colors, merch, and more!
Jams, jellies, preserves, marmalade. So many kinds of fruit spreads, but how are they made? How do they go from fruit to gooey spread? How are they delicious? What the chemistry here, and how has it been going on long before we understood it?
We all know that maple syrup is one of Canada's most popular gifts to the world, but what really is it? Why do maple trees (and other trees) even have sap? And is there any chance that there's cool surprising chemistry things going on in there? Well you'll have to listen to find out.
Well here in Texas, we just suffered through an intense freeze. And many a plant became a casualty of the cold, but why? What's going on at the molecular level that causes freezing temperatures to be bad for many plants? And is talking about this even chemistry? Let's find out.
Wait, muscles are biology right? Well they're also chemistry. And guess what, muscle soreness and cramps are also chemistry. And believe it or not, the mystery of muscle soreness is much bigger than you might expect. Check it out!
In this month's bonus episode, we share a special old Q&R that we've had in our back pocket for almost a year! Enjoy!
This might be one of the best chances to both listen to AND experience chemistry at the same time. Grab a bath bomb, fill up the tub, and let's find out how these friendly bombs work. How do they fizz up? How do they suddenly smell? Where do the colors come from? Can they make bath scientifically better? Let's hop in.
We have a very special guest this month, Stephanie Ryan Ph.D. aka @letslearnaboutscience (on Instagram)! Stephanie leads us through some cool experiments you can do at home using vinegar and baking soda. Be sure to check Stephanie out on Instagram, and look for her book "Let's Learn About Chemistry" wherever you buy your books!
Wow sunglasses sure are cool. What's the coolest thing about them? Is it how cool they make us look and feel? Or is it the chemistry inside them? We'll let you decide, but we think you'll be surprised to find out how significant a role chemistry plays in the making of your shades.
The sun. It's nice, it's warm, it helps things grow, it helps us see, it helps us exist in the first place. But it's also a massive burning molten ball of radiation and ultraviolet rays. So how does our mysterious yellow friend fade the poor items we leave outside? Let's find out. Don't hurt us, yellow friend.
Dryer sheets. They smell good. They make our clothes soft. They get rid of static. But how? How is one little sheet allowed to solve that many problems? What are they made of? Are they bad or good or neither?
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 salt, vinegar, and pennies?
Glass. The more you look at it, the more clear it becomes that it holds some serious mysteries. So what really is glass? Is it a liquid? How is it different from typical solids? Does it flow and ooze over time? Is that why old windows are thicker at the bottom? Let's find out!
In this month's bonus episode, Melissa and Jam respond to comments and questions about salt, bread that tastes like bananas, sunscreen on fences, AND improvements to our chemistry analogies!
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!
