Reactions

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!

*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!

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?
