Science Doesn't Understand How Ice Forms
S10 E6 - 10m 31s
This video contains incredible macro footage of supercooled water droplets nucleating ice. All George wanted to do was make a crystal-clear ice cube. Instead, he ended up rediscovering dendritic crystal growth, a beautiful phenomenon first described in the 17th century. You’ll never look at your freezer the same way again.

Is There a Quick Fix for Ocean Acidification?
S10 E5 - 13m 12s
The ocean is getting more and more acidic. Can we solve it by emptying a giant bottle of antacid into the ocean? No… but the idea of lowering the ocean’s acidity in order to decrease global carbon dioxide levels isn’t all bad. Let’s dive into the science behind ocean alkalinization, and how it could be one part of a larger solution to our global climate crisis.

I Reinvented a 300-Year Old Drink
S10 E4 - 16m 56s
Adding milk to an alcoholic drink and then curdling that milk is a 300-year-old preservation technique that was used by none other than Ben Franklin. Join George as he discovers the chemistry that makes this technique so useful, and learn how to make the best espresso martini you’ll ever taste.

We Are Made of Star Stuff
S10 E3 - 10m 13s
For years, scientists thought some complex molecules could only be formed on Earth. But what if we found these kinds of molecules out in space after all? In this episode of Reactions, we explore new findings that show complex carbon ring structures can be formed in space, and what that might mean for biology, chemistry and our own chemical history!

Does Toyota Know Something That We Don’t?
S10 E2 - 12m
*Note:* the model piston we used in this video shows air and fuel entering the cylinder together. This design was prevalent in engines until roughly the 1990s. These days, air and fuel enter separately. The combustion process and piston movement are the same!

Can Science Beat Counterfeit Detector Pens?
S10 E1 - 10m 20s
Counterfeiting money is wrong. Obviously. But if you wanted to take your totally not real money and fool a counterfeit detection pen, could you do it?
