So, is it ever right to be angry? And if so, when? Delaney Thull takes a philosophical look at this powerful emotion. Lesson by Delaney Thull, directed by Cara Watson.

One of humanity's most time-honored condiments - Dan Kwartler

Trace the history of ketchup, from the condiment’s origins in 3rd century China to becoming a staple of American cuisine. -- In the mid-18th century, England was crazy for ketchup. The sauce was a staple, but this ketchup wasn’t the ubiquitous red goop you’re familiar with today. In fact, it was a sweet and savory brown sauce that didn’t even have tomatoes in it. So where did this early ketchup come from, and how did it become the dip we know and love? Dan Kwartler traces the condiment's history. Lesson by Dan Kwartler, directed by Denys Spolitak.
