Smarter Every Day

Smarter Every Day is the channel of Destin Sandlin, who introduces himself on Instagram simply as 'I'm Destin.' He is an aerospace engineer from Alabama who built the channel around hands-on science exploration rather than studio-style explainers.

Yes — Destin Sandlin has a real aerospace engineering background and has worked with organizations including NASA and the U.S. Army. That professional credibility is a big reason he gets access to facilities like nuclear plants and military hardware that most science communicators never see.

Destin is based in Huntsville, Alabama — often called Rocket City because of NASA's Marshall Space Flight Center located there. That proximity to aerospace and defense infrastructure shows up repeatedly in the types of access and topics his channel covers.

Yes — Destin filmed an episode inside an operating nuclear plant that he says genuinely changed how he thinks about radiation. The video focuses on demystifying nuclear energy by showing the reality of what workers experience day-to-day, rather than relying on the fears most people bring to the subject.

The Smarter Scrubber is a product Destin attempted to design and manufacture entirely inside the United States, documented as a full channel experiment. The episode explored the real-world friction of American manufacturing — supply chains, tooling, costs — rather than simply debating the topic in the abstract.

The episode 'Why Do Spinning Things Do This?' digs into gyroscopic precession — the counterintuitive effect where a spinning object resists changing its orientation and instead moves perpendicular to whatever force you apply. It's a signature Smarter Every Day format: take a phenomenon that seems like magic and walk through the physics until it clicks.

Yes — Episode 310 is titled 'Pompeii Changed How I Think About The Roman Empire,' where Destin visits the archaeological site and processes what he sees through a science-and-engineering lens rather than a purely historical one. It represents the channel's growing pattern of blending site visits with deeper conceptual takeaways.

Destin runs a recurring #ThankYourTeacher initiative encouraging his audience to reach out to a teacher who sparked their curiosity. It reflects his belief that science enthusiasm is usually ignited by a specific person, and it appears consistently enough across his posts to be treated as a core part of the channel's identity.

Confirmed recent sponsors include KiwiCo (a hands-on STEM subscription kit service), Henson Shaving, and AnyDesk (remote desktop software). KiwiCo is a particularly natural fit given that Destin's audience skews toward technically curious adults and parents who'd be drawn to hands-on learning products for their kids.

Smarter Every Day has surpassed 11 million subscribers on YouTube, making it one of the largest independent science channels on the platform. Engagement runs well above the category average, which reflects an unusually active and loyal audience for a channel of that scale.
