LEGO SUBMARINE BUT IT KEEPS GETTING BIGGER | Comparison

Started with a tiny 2-brick LEGO submarine… and kept going until it hit almost 10,000 bricks 🌊 Every sub in this video is a different build: a World War Two U-boat, a yellow research sub, the American Gato and Ohio, the giant Soviet Typhoon and a modern Virginia attack sub, each in its own colors. Along the way you'll find out how submarines dive, how they see in the dark with sonar, and how deep a submarine has ever gone. Which one is your favorite? Let me know in the comments!
