TedEd - Deconstructing Macaroni Salad
This video was commissioned by TedEd as a two part series on the fundamentals of chemistry.
What’s in macaroni salad? Break down the pasta, mayonnaise, vinegar, mustard, vegetables, etc., and you’re left with a bunch of molecules. This video uses a delicious recipe to exemplify three types of mixtures (solution, colloid and suspension), while reminding us that we’re all made of the same stuff.
What do macaroni salad and gasoline have in common? They are made of exactly the same stuff -- specifically, the same atoms, just rearranged. So, while we put the former in our mouths and the latter in our cars, they are really just variations on the same atomic theme. This video breaks macaroni salad down to its smallest chemical components.
