Capturing the natural beauty of chemistry I find that chemistry is often taught poorly or without a purpose. Because of this, people tend to lose interest and sometimes even start to hate it. In each video that I make, I try to balance theory with purpose. My goal is to capture the natural beauty of chemistry in fun and interesting ways. In terms of education, I have a BSc in Biochemistry, with a minor in pharmacology. However, I've always been a lot more drawn to applied chemistry. So after finishing my degree, I worked as a lab tech in an organic lab, and then as a chemistry grad student. However, I ended up leaving my graduate studies early to focus on this channel. Now, making chemistry videos has become my full-time job!

Video Description

What I have here is 100g of pure gold, and at around $57 US per gram, it's worth about $5700. It's one of the most expensive, and precious things that I own, but I think I'm just gonna destroy it using acid. Dissolving this gold bar is actually part of the process that I did to make purple gold! WARNING: Aqua Regia is an extremely corrosive mixture of nitric acid and hydrochloric acid. It was handled in a controlled environment and it's very dangerous if used improperly. #shorts
