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.

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.

I thought this was really interesting, and I decided to try making pure 1-octen-3-one myself…
