Whenever I fill up my car’s gas tank I’m thankful that I don’t have a car that requires high octane gasoline. What is high octane gasoline anyway? Is is really significantly better than regular unleaded gasoline? And why is gasoline “unleaded?” Those questions and more are answered in this relatively new Reactions video. 

Applications for Education

Over the years I’ve had lots of students who were aspiring mechanics. One that I had last year was always moaning about how his car could only run on high octane gasoline and that it was so expensive. A video like this one could help those students understand how gasoline is actually produced and how the octane rating is measured.

On a related note, here are some good tools for annotating videos.
