Mythbusters has been off TV for a while, but you can now watch a bunch of their classic episodes for free on YouTube. One of those episodes tested if you could make a giant ball of LEGO that would roll down a hill and over a car! Obviously, it is possible to make a giant LEGO ball, so the myth centered more on its weight and the number of LEGO bricks it would take. The ball they constructed was amazing, made of solid LEGO bricks where some large builds may be hollow or use DUPLO at their core. The Mythbusters crew even visited their local LEGOLAND California park for some advice and also took in some rides while they were there.

I’ve had a chance to build a LEGO ball before, but on a much smaller scale at LEGO Discovery Center Atlanta. One of the best parts of a visit is the ability to work with a master builder to make a small LEGO build yourself. On one of my trips down there we built a LEGO ball. It was a different design than the Mythbusters used and significantly smaller, about the size of a Ping pong ball, but still a lot of fun. If you head down to LEGOLAND Florida you can currently see another slightly larger LEGO ball as part of the FIFA® World Cup 2026 Experience. One of the displays there has several brick-built versions of soccer icons including Cristiano Ronaldo, Kylian Mbappé, Vini Jr. and Lionel Messi, each with a LEGO soccer ball.

So what happened in the video? No major spoilers here other than to say they did build a giant LEGO ball with the help of some volunteers and a LEGO artist who let the borrow a large amount of bricks. I won’t ruin the ending for you, but the result certainly wasn’t what I anticipated. You can watch this 2 minute summary video about the Mythbuster LEGO ball build if you want to find out. for yourself. This was a fun myth to watch them test and it was great that LEGOLAND was involved in the effort. Give the video a watch and you’ll certainly walk away with an greater appreciation of the time and energy it takes to make a giant LEGO build.
