What’s Inside? Family is a popular YouTube channel and online brand known for its engaging and educational content centered around curiosity, exploration, and family-friendly entertainment. Created by father-son duo Dan and Lincoln Markham, the channel began in 2014 with a simple, intriguing idea: discovering “what’s inside” everyday objects. The concept quickly captured viewers’ attention as Dan and Lincoln began cutting open a variety of items to reveal their interiors. What started as a school science project soon evolved into a YouTube sensation, with millions of subscribers and billions of views. Their videos combine an educational approach with fun and discovery, making them a hit with viewers of all ages.
The origins of What’s Inside? can be traced back to a second-grade school project. Lincoln, who was then about seven years old, had to create a presentation on how things work, which sparked the initial idea of exploring the insides of objects. Dan, Lincoln’s father, suggested they cut open a sports ball to show its interior. The result was a simple but fascinating video that they uploaded to YouTube. This video unexpectedly gained traction, and soon the pair found themselves experimenting with cutting open various items to satisfy viewers’ curiosity.
Dan and Lincoln’s engaging personalities and dynamic relationship have been central to the channel’s appeal. Dan, a former pharmaceutical sales representative, has a calm and reassuring demeanor, while Lincoln’s natural curiosity and youthful enthusiasm make him relatable to young audiences. The chemistry between father and son has helped the channel grow steadily as they tackle increasingly interesting and complex objects. As the videos became more popular, Dan decided to make YouTube his full-time job, devoting himself to growing the channel and creating content that continues to excite viewers.
