Reactions is a show that uncovers the chemistry all around us.
From Reactions. Why was the West Coast sky bright orange? This week we break down the Mars-like haze and how climate change is involved. #orangesky #climatechange #wildfires Take the PBS Digital Studios annual survey: http://to.pbs.org/2020survey You might also like: How Are Forest Fires Put Out? https://youtu.be/fNGq8hEuNb8 Why This Town Has Been On Fire For 50…

From Reactions. Cellulose is everywhere. In fact, it is the most abundant organic molecule on the Earth! It’s in (but not limited to) our food, clothing, and plastics, and the cellulose compound nitrocellulose is used in explosives but also in things like x-rays, early silent films and nail polish. In this episode of #Untold, a…
From Reactions. When you think of batteries, you might think of the thing your watch or car needs to run. But as we move toward producing and storing more renewable energy (like solar and wind) we have to start thinking bigger. In this episode of #Untold, a new #YouTubeLearning series from ACS, PBS, and YouTube,…
From Reactions. The sun is essential plant food that’s heating our planet, but we don’t often think about the wild things happening on and below its surface. In this episode of #Untold, a new #YouTubeLearning series from ACS, PBS, and YouTube, we talk about those wild things, and how they can affect us all the…
From Reactions. It might feel like they’re making us cooler, but refrigerators and air conditioning are actually making our world warmer. Yes, they use a huge amount of electricity, but many older cooling methods also released tons of molecules that are still hanging around, shredding our #ozone layer. In this episode of #Untold, a new…
From Reactions. Our planet has been rocked by many-a-meteorite, and they’ve left not just themselves as space debris but also craters and even molecules needed for life. Now we’ve started to travel to them, and they might be a key part of our forays into deep space. In this episode of #Untold, a new #YouTubeLearning…
From Reactions. On August 21, 1986, violent explosions rocked Cameroon’s Lake Nyos. A wave of water over 15 meters (around 50 ft) high flattened vegetation along the southern shore, but a second deadly, nearly invisible wave of carbon dioxide blanketed the nearby towns, suffocating residents and animals. In this episode of #Untold, a new #YouTubeLearning…
From Reactions. Maybe you already knew that deadly algal tides discolor ocean waves, deplete the water of oxygen, and release toxins that can kill a huge range of ocean critters, but did you know that the tiny organisms that cause red tides are also an extremely important part of our ecosystem? In this episode of…
From Reactions. When you think “molasses,” you probably think “slow, sticky,” or “totally boring,” but in January, 1919, a tsunami wave of molasses destroyed Boston’s North End, killing 21 people and leaving another 150 injured. In this episode of #Untold, a new #YouTubeLearning series from ACS, PBS, and YouTube, we get into the science behind…
From Reactions. On January 28, 1986, the Challenger Space Shuttle broke apart just 73 seconds into its flight. All seven crew members aboard were killed and space travel was changed forever. In this episode of #Untold, a new #YouTubeLearning series from ACS, PBS, and YouTube, we explain the science behind this tragic, avoidable accident, and…
From Reactions. Out in the deep swims an elusive whale who has never been seen, but has been heard for years. The whale sings a song outside the normal whale-song frequency. Does that mean none of its fellow whales can understand it? In this episode of #Untold, a new #YouTubeLearning series from ACS, PBS, and…
From Reactions. How hard could roasting beans at home really be? Sam and George go head-to-head in a coffee roasting competition to find out, and Candy Schibli, the founder of Southeastern Roastery (https://www.southeasternroastery.com/aboutsoutheasternroastery.html#), where she’s also head roaster, provides expert advice..

From Reactions. On July 7th, we’re launching a new Youtube Learning series! Untold is all about science—chemistry, physics, astronomy, and geology—and how it helps us learn about the crazy, fascinating things that happen in the world around us. Untold is hosted by Dr. Alex Dainis, who can’t wait to share stories of exploding lakes, a…
From Reactions. Sure, you’ve got a product that says “kills germs” under your sink, but will it really destroy the new coronavirus on surfaces? Turns out that if you’re using a disinfectant like a regular cleaner, you might not actually be disinfecting at all. To make sure you’re destroying 99.9% of viruses and bacteria, doing…
