Mark Rober’s CrunchLabs
What's the Story?
In MARK ROBER'S CRUNCHLABS, the YouTuber moves some of the most popular episodes from his channel onto the Netflix streaming platform. A former NASA engineer, he is super skilled at building different types of robotic gadgets and elaborate experimental setups. He fills a pool full of Jell-O, makes "elephant toothpaste" that shoots hundreds of feet into the air, and trains his pet octopus to navigate an underwater maze. While he's creating his experiments, he explains science and engineering concepts to the home viewer. At the end of each episode, viewers get to watch a truly amazing science experiment come to life.
Is It Any Good?
The science content in this series is fantastic, which is one reason why Rober has 72 million subscribers on YouTube. Mark Rober's CrunchLabs doesn't bring anything new to the table, since the episodes are plucked directly from the YouTube channel. Rober himself is super entertaining to watch, and successfully walks the tightrope of appealing to "bro" culture without being over-the-top. Grown-ups will probably wish that CrunchLabs didn't have literal toy commercials intertwined with the science content, since Netflix shows don't traditionally hawk products like YouTube does (though maybe having your child beg for an educational STEM toy is not the worst possible outcome).
Talk to Your Kids About ...
Families can talk about how Mark Rober's CrunchLabs has segments that sell his CrunchLab STEM kits. How are these short parts of the episode different than advertisements you might see on TV or on YouTube? Why do you think the show's makers included these types of ads?
Mark has a tremendous amount of curiosity. Can you think of an example of how his curiosity lead him to keep going and trying different things until his experiment worked?
Mark does super extreme versions of science experiments on the show, but is there anything you saw him do that you want to try a smaller version of at home?
