'Brick by Brick' – "Brick by Brick," a new exhibition at Chicago's Museum of Science and Industry showcases the work of professional Lego builder Adam Reed Tucker.
America Eagle Roller Coaster – The exhibition includes a plastic building block replica of the wooden American Eagle roller coaster at Six Flags Great America theme park in Illinois.
Toy ride – The Lego American Eagle is 12 feet long, took 55 hours to design and 70 hours to build. It's made up of 14,500 bricks.
Lego Colosseum – The Roman Colosseum took Tucker 120 hours to design and 75 to build. It's one of many architectural wonders of the world on display at the exhibit.
Egyptian pyramids – This Lego replica of the Great Pyramid of Giza is 12 feet long and took 50 hours to design. The "Brick by Brick" exhibition is on display until February 2017.
Rare Lego – The pyramids took 45 hours build and are made up of 24,000 bricks. A close look reveals that the corner contains rare Lego pieces that are no longer made.
Hoover Dam – Tucker even manages to create a replica of the Colorado River's Hoover Dam, with plastic instead of concrete.
Under construction – The semi-complete Lego dam replica stands at 5 feet tall, took 215 hours to design and 160 hours to build. It uses 42,800 bricks. The original, which straddles the Nevada-Arizona border, took five years, opening in 1936.
ISS – The Lego recreations are not limited to earthbound wonders. There's even a model of the International Space Station.
'Creativity and imagination' – Tucker, he says, hopes "people looking at my work will also appreciate and learn about each architectural wonder and the creativity and imagination that's possible with the Lego brick."
Sculptural form – "As I design and build, I gain a greater appreciation for the structure I am working on and try to capture the essence of the building in its sculptural form," Tucker says.
Golden Gate Bridge – Despite the incredible attention to detail, Tucker says his work is often the result of trial and error.
Disney castle – Sprinkling some Disney magic on the exhibit, Tucker built a replica of Cinderella's Castle. He explains, "I'm just an artist trying to repurpose a child's toy as a creative tool."
Burj Khalifa – Tucker's plastic replica of Dubai's Burj Khalifa, the tallest building in the world, took "only" 16,500 bricks to build, 45 hours to design and 60 hours to build.
Gateway Arch – In real life, the Gateway Arch monument in St. Louis, Missouri is covered with stainless steel.
One World Trade Center – The real version of the One World Trade Center in New York City is the tallest skyscraper in the Western Hemisphere.
Lego challenges – The Chicago exhibition encourages visitors to try hands-on challenges like building and testing structures that could withstand earthquakes and high winds.
