Maple trees + good timing + basic chemistry = maple syrup. But Science Friday takes us behind the scenes of maple syrup research to show that there’s much more to it than that. While the tradition has been to tap fully grown wild trees – commercially with lots of plastic tubing – recent experiments at University of Vermont’s Proctor Maple Research Center have found that harvesting from the cut tops of juvenile trees might yield 5 to 6 times per acre, surprisingly without harming the young trees.
Lots of questions about this one: What are the other differences between the farm vs forest model of growing trees? Does this new process affect the local birds or creatures underground? What do these young trees look like in 20 years? What questions do you have?

This promotional video for NOMOS Glashütte is delicate, detailed, quiet, and fascinating. Master craftspeople assemble the mechanical timepiece’s gears, hands, and other tiny parts with precision as we Look Over the Watchmakers’ Shoulders.
This street vendor makes popcorn with an explosive, pressure-cooking, popcorn cannon contraption, a centuries-old method. The video was filmed in Zhengzhou, China, but we’ve watched videos of this in South Korea, too. And of course, Mythbusters has looked into it, video below. Boom!

We know that sugar is a big part of candy, ice cream, and sweet drinks, but did you know that added sugars are included in 3/4 of the 600,000+ products found in the average grocery store? And that it can go by 56 different names?
Watch this super useful TED Ed by Robert Lustig, with animation by The Tremendousness Collective, to learn more about the different kinds of sugar inside the foods that we eat, and how it interacts with our bodies: Sugar: Hiding in plain sight.
