Let's Settle This: How to Care for Cast-Iron
 
03:21
This week Reactions takes chemistry to the kitchen, or at least to cast iron skillets. Science helps to answer how we should take care of these bad boys and how to season them. Cast-Iron skillets are one of the kitchen's ultimate multitools with some big time advantages over your everyday, stock aluminum pan. Today we're taking a look at why these pans rule, and for you kitchen know-it-alls out there, pay close attention: we're using chemistry to prove the right way to season and treat a cast-iron skillet.

Why is Pizza So Good?
 
03:18
This week Reactions is talking about the science of pizza. Delicious chemistry! Whether it’s a plain cheese, a deep-dish stacked with meats or a thin-crust veggie delight, there’s just something about pizza that makes it delicious. There’s a lot of chemistry that goes into everything from dough to sauce to toppings to, of course, cheese. There’s also a very specific chemical reaction at work on every single slice, no matter what toppings you choose. It's called the Maillard Reaction, and it's what causes the browning of the dough and toppings, as well as the release of some delicious compounds.

The Science of Distance Running
 
04:24
This week Reactions is taking a look at the chemistry behind marathon running. The science that goes on in athlete's bodies is pretty neat. Athletes push their bodies for miles and deal with cramping, dehydration and every runner's worst fear: that extreme form of fatigue called "hitting the wall." Why is endurance running so difficult? With the New York City Marathon kicking off this Sunday, Reactions runs through the science of distance running: why muscles burn, how sweat cools the body and the chemistry of runner's high.

You're Cleaning Your Contacts Wrong, Probably
 
05:01
Follow us over to Gross Science! https://youtu.be/wRMKzsU9zec This week Reactions is checking out the chemistry behind cleaning your contacts. Ninety-nine percent of adults who wear contacts admit to breaking some cardinal lens rules: sleeping in them, washing them in water and so on. Many contact-wearers may brush off these accidents, but improper lens care can have gross — and sometimes serious —consequences. This week, Reactions collaborates with Anna Rothschild from Gross Science to explain why unclean contacts can cause problems and how to prevent them.

Why Are Avocados So Awesome?
 
03:10
This week Reactions takes a look at the chemistry behind our most beloved fruit; avocados. Whether they’re in a big bowl of guacamole or scooped on top of your salad, avocados enjoy a special place in our hearts and stomachs. On top of being tasty, avocados are a noted superfood with a number of fantastic health benefits. This week, Reactions has mashed up some fantastic avocado facts, as well as some cooking tips from the pros. ++Note: There is a typo. The video mentions monosaturated fatty acids. Like unicorns, these do not exist. It should be monoUNsaturated fatty acids. Apologies, and thanks to the internet for pointing it out.++ ++2nd Note: Another eagle-eyed and eared viewer pointed out that we say vitamin B12. There is no B12 in avocados. There is, however, a TON of B6. So go get that B6 from your guacamole, get your B12 from herring, clams or crab.

How Do Snowflakes Form?
 
02:40
Snowflake images from Alexey Kljatov: https://www.flickr.com/photos/chaoticmind75/ This week Reactions is taking a microscopic look at snowflake science and how they form. Huge snowstorms and blizzards dump feet of snow from the skies every year, and that means trillions of tiny snowflakes. Through advances in crystallography, scientists have learned a lot about the structure of snowflakes. While they all start pretty much the same, once they start crystallizing, it’s true that no two snowflakes are alike. In fact, the number of possible shapes is staggering.

How Smartphones Keep You Awake
 
02:51
This week Reactions is looking at the science and chemistry behind your smartphone that keeps you awake at night. Your smartphone addiction isn't helping you sleep. In fact, an obscure chemical reaction may be keeping you awake. The latest Reactions video looks at the process that connects your late-night texts to your lack of sleep and how to improve your sleep hygiene. Your smartphone, tablet and other devices emit large quantities of blue light wavelengths. This tells your body "wake up!" when you should be getting ready to sleep. Your body gets that signal through melanopsin, a protein that hangs out behind your eye and undergoes a chemical change that in turn signals your body's master clock. So turn off your iPhone long before you go to bed. It'll be there in the morning. Thanks to Brian Zoltowski of Southern Methodist University.

How to Survive a Real-Life "Fallout"
 
04:08
This week Reactions is checking out some Fallout science. Does chemistry allow you to survive a real fallout? It’s a big week for gamers now that the long-anticipated Fallout 4 video game is out. The series takes place in a world decades after nuclear war has destroyed most of civilization. Only those who hid in fallout shelters survived. While this idea works in a fictional game universe, could humans really survive for years or even decades in such a shelter? This week, Reactions looks at the basics of survival in a world riddled with radiation.

How Can You See an Atom?
 
05:36
This week Reactions takes a close up look at the science of how we can see an atom. Since ancient Greek times, philosophers and scientists have tried to figure out what an atom looks like. For a couple thousand years, humans could only speculate on the structure and other properties of the smallest unit of matter. It wasn't until the 1980s that chemists could see individual atoms. Bestselling author Sam Kean takes us through the nearly 2,400-year quest to see the atom in a new episode of our "Legends of Chemistry" series.

Are Invisibility Cloaks Possible?
 
04:01
This week Reactions is taking a look to see if science and chemistry could make invisibility cloaks possible. Have you ever wished you could hide under an invisibility cloak like Harry Potter or conceal your car with a Klingon cloaking device like in Star Trek? In a special bonus episode of Reactions, we celebrate the International Year of Light by exploring the science behind light, sight and invisibility. Though we can’t make ourselves invisible yet, some promising research may light the way – or rather, bend the light away. This episode of Reactions was produced in collaboration with the journal ACS Photonics. For more information on ACS Photonics, please visit: http://pubs.acs.org/journal/apchd5.

This week Reactions takes a look at the chemistry behind electrolytes and sports drink science. Sports drink commercials love talking about them, but what are electrolytes, why do we need them, and what happens if we don’t have enough? Electrolytes are salts that, once in our bodies, help our cells move water around. They also enable the nerve impulses that keep our hearts beating, our lungs breathing and our brains learning. But we can also lose them — for example, by sweating. Given all the ins and outs of electrolytes, should you reach for that bright orange sports drink after running around the block?

Reactions won't put you to sleep this week with our video on the chemistry behind anesthesia and how it works. October 16 is World Anesthesia Day, celebrating the 170th anniversary of the first successful demonstration of surgical anesthesia. Prior to then, surgery was really unpleasant, to put it mildly -- surgeons turned to alcohol, narcotics and even smacking their patients on the head to induce unconsciousness. Fortunately, anesthesia now allows tens of thousands patients every day to avoid the pain and memories of their procedures. But how does anesthesia work?

How Do Deodorants and Antiperspirants Work?
 
02:56
This week Reactions is getting into some stinky science. We're looking at the chemistry of body odor and how deodorants work. If there is one thing everyone on Earth has in common, it's that we all absolutely stink. Luckily we have deodorants and antiperspirants to help us get over that fact, but chemically speaking, how do these products actually work? This week on reactions, we're taking a look at body odors, and how we drape a tarp over them with chemistry.

How Do Airbags Work?
 
03:34
Check to see if your car is part of the Takata airbag recall: https://www.nhtsa.gov/recalls If you’re in a car accident, you want to be sure your airbags protect you. And they work because of chemistry, with some physics thrown in. This week on Reactions, we’re talking the science of airbags. And remember: Airbags are meant to work in conjunction with seatbelts, so buckle up! [Pinned comment: In the aftermath of a crash, you might notice a puff of white powder and a funny smell. In older model cars, that’s cornstarch or talcum powder used to lubricate the bag itself, but in more recent vehicles, it’s the actual byproducts of the airbag reaction.] Subscribe! http://bit.ly/ACSReactions Facebook! http://facebook.com/ACSReactions Twitter! http://twitter.com/ACSReactions Instagram! https://www.instagram.com/acsreactions/ Tumblr! http://acsreactions.tumblr.com/ You might also like: Small Bottle, HUGE Fireball (How Flame Jetting Works) https://youtu.be/5sfUl6GIdYo Chemtrails https://youtu.be/ZonPvpgcBc0 What Makes Smartphones Explode? https://youtu.be/pY-kzHn9kvo No, Your Microwave Isn't Dangerous - Food Myths #1 https://youtu.be/0yi6EzAK66s Credits: Producer: Sean Parsons Writer: Alexa Billow Scientific Consultants: National Highway Traffic Safety Administration (NHTSA) Sources: https://www.youtube.com/watch?v=mWSlwhYyOhI http://www.chemistry.wustl.edu/~edudev/LabTutorials/CourseTutorials/bb/Airbags/151_T5_07_airbags.pdf https://www.scientificamerican.com/article/how-do-air-bags-work/ https://www.thoughtco.com/history-of-airbags-1991232 http://web.bryant.edu/~ehu/h364proj/sprg_97/dirksen/airbags.html https://www.consumeraffairs.com/news04/2006/airbags/airbags_invented.html https://paleofuture.gizmodo.com/a-brief-history-of-air-bags-and-the-future-of-driverles-1634903213 https://www.nhtsa.gov/equipment/air-bags https://www.quora.com/Why-do-airbags-smell https://www.popsci.com/how-airbags-are-supposed-to-work#page-2 https://pubs.acs.org/doi/abs/10.1021/ed073p347?journalCode=jceda8 https://cecas.clemson.edu/cvel/auto/actuators/airbag.html Ever wonder why dogs sniff each others' butts?

How Is Whiskey Made?
 
04:55
Special thanks to District Distilling in DC! You can find more about them here: http://www.district-distilling.com/ Reactions took a field trip to learn about the chemistry involved in distilling whiskey. Yes there's all sorts of science in this delicious drink. Since water and ethanol, along with tasty flavors, have different boiling points, they can be separated by carefully heating the mash that starts off every whiskey. Each distillery carefully protects their still design, engineered to create their signature liquor. The strongest flavors take aging, but might some innovative whiskey makers find a way to hack maturation time?
