View this post on Instagram Instagram PostThe challenge in episode 9 of LEGO Masters saw the contestants sketching plans to create a functional great ball contraption, hoping to leave a lasting impression on the experts with their spots in the competition at stake. The four teams competing in the race were Ben and Michael, Ian and Sage, Anthony and Joe, and Corey and Rebecca.The task proved difficult for many, as they struggled to meet the judges' expectations. Not only were they required to create a unique contraption, but they also had to match and coincide their contraptions to those of their competitors to move the ping pong ball from one side to the other.First up were LEGO Masters stars Ben and Michael, who created a "lost meatball" contraption that rolled a meatball into the pantry. While the experts appreciated the presentation and story behind it, they were concerned with the build's functionality.

They incorporated their builds from throughout the season into the contraption, capturing their experience on the show as the ball traveled from one point to the other. However, the experts remarked that the build was a little simplistic.Anthony and Joe described their build as telling the story of "Anthony and Joe escape from mom." It showed a child getting lost in an amusement park and doing everything his mother would never permit, with a ball chasing him the whole time. The LEGO Masters judges appreciated their craftsmanship, but more so, the story behind the creation.The last team up for deliberation was Corey and Rebecca. They presented the experts with a hairbrush-themed build, which also included bumpers to manage the speed of the ball.

Despite a few small glitches, the ball managed to complete its course. After reviewing the performances of the teams, the LEGO Masters judges sent Anthony and Joe to the series finale. The second team through was Sage and Ian, which meant Corey and Rebecca, as well as Ben and Michael, were in the bottom two. Both displayed potential, but Amy and Jamie decided to advance Ben and Michael, eliminating Corey and Rebecca from the race.LEGO Masters can be streamed on Hulu.
