I've often said that Sesame Street's "Making Crayons" is the best two minutes to ever air on TV. It is mid-century Sesame Street at its best.
But Mr. Rogers also had a great "how crayons are made" video. And if you have a kid, you know that the new Mr. Rogers is Daniel Tiger. (If you don't have a kid, here's the scoop on Daniel Tiger's Neighborhood. Long story short, it's a cartoon that takes place in the Neighborhood of Make-Believe.)
I was watching Daniel Tiger with the kid the other and Daniel took "A Trip to the Crayon Factory." I'm really happy to see this same concept is being passed on to a new generation. I can only hope the kid's memory of this episode are as rose tinted as mine are of the "Making Crayons" segment.
