Reactions is a show that uncovers the chemistry all around us. We answer the burning questions you’ve always wanted to ask:

-How can I get my smartphone battery to last longer?
-What if humans could photosynthesize?
-How can I get my teeth to look whiter?
-Why is pizza so delicious?
-Is it OK to pee in the pool? (Spoiler: No. No it’s not. Stop it.)

Reactions are happening everywhere. But the best ones are right here on YouTube. Subscribe!

Chameleons Are Masters of Nanotechnology

What do chameleons have to do with nanotechnology? These color-changing lizards are some of nature’s wackiest animals, all because they’re masters of pigment and light.

How Do Airbags Work?

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?

Small Bottle, HUGE Fireball (How Flame Jetting Works)

Learn more about CuriosityStream at https://curiositystream.com/reactions (CODE: reactions) Pouring gasoline, alcohol, or other fuel over a flame can cause a ten-foot fireball to shoot out and engulf an unsuspecting victim. This week on Reactions, we’re explaining the science of flame jetting and why it happens. Also, if you’re a chemistry teacher: the ACS Committee on Chemical Safety issued a safety alert (see link below), which recommends that the Rainbow Demonstration (performed on an open bench using flammable solvents like methanol) be discontinued immediately. This demo presents an unacceptable risk of flash fires and deflagrations that can cause serious injuries to students and teachers. Alternative experiments (see link below) are available that demonstrate the same rainbow colors but don’t use flammable solvents on an open bench. Safety alert: https://www.acs.org/content/dam/acsorg/about/governance/committees/chemicalsafety/publications/ccs-chair-rainbow-demonstration-cen-comment.pdf Alternate demos: https://www.acs.org/content/acs/en/chemical-safety/demonstrations-and-experiments.html 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: Why You Shouldn't Pee on a Jellyfish Sting: https://www.youtube.com/watch?v=KDj2t4-bn1g How Does Alcohol Get You Drunk: https://www.youtube.com/watch?v=1xVqwYxe4Gw Why This Town Has Been on Fire for 50 Years: https://www.youtube.com/watch?v=fsgqy5FYP2c Mind-Blowing Movie Explosions Explained: https://www.youtube.com/watch?v=3e839o4YGao Credits: Producer: Sean Parsons Writer: Alison Le/Alexa Billow Scientific Consultants: Adam St. John P.E., Scott Ayers P.E.

Chemtrails

This week Reactions is taking science to the skies and checking out the chemistry behind chemtrails, or more accurately, contrails. It’s easy to look at the white trail behind a jet aircraft and imagine all manner of chemicals raining down from above. However, airplane contrails are simply what happens when the chemistry of burning jet fuel meets the chemistry of air.

The Disappearing Spoon, The Rooster and the Bearded Russian

This week on Reactions, we look at the chemistry of gallium, the science behind the holes in the periodic table, and the history of how the elements fell into place. Some chemists might see the periodic table of elements as a holy testament to the power of science. However, when it first debuted, it was a different kind of holey, and its journey to classroom walls everywhere had a whole lot of bumps. Watch as Reactions digs into the history of the periodic table with the help of a vanishing spoon, a man named after a rooster, and a bearded Russian.

Do Ketogenic Diets Really Work?

This week Reactions tackles the diet fad that never dies--low carb. There's a lot of science that goes on with the keto diet and cutting out carbohydrates. Low-carb diets were a thing in the late 90s and they’re still a thing now. But why does this fad have staying power? Is it because the touted benefits are real? Or is that greasy, low-carb burger fried in snake oil?

The Periodic Table Table

Don't miss out--subscribe! http://bit.ly/ACSReactions Some people collect stamps. Wolfram Research co-founder and author Theo Gray collects elements. Step into his office, and you'll see a silicon disc engraved with Homer Simpson, a jar of mercury, uranium shells and thousands of other chemical artifacts. But his real DIY masterpiece is the world's first "periodic table table." Within this masterfully constructed table-top lay samples of nearly every element known to man, minus the super-radioactive ones. Theo Gray is 2011 winner of the ACS Grady Stack Award for Interpreting Chemistry for the Public. The Periodic Table Table is a testament to Theo's love for chemistry -- as well as his Ebay buying habits -- and is full of fascinating stories.

The One Where We Put Stuff in Acid

Subscribe! http://bit.ly/ACSReactions Acids are reactive, and even weak acids like vinegar can wow students with their reactivity. But strong acids can really put on a show, dissolving otherwise relatively inert metals. And aqua regia, or royal water, is a mixture of hydrochloric and nitric acids that can dissolve gold, a noble metal.
