This year’s theme, The Great Adventure, followed two tiny balls on a story-driven journey through the massive build. Along the way, the balls crossed an ocean on a ship, scaled a mountain, tumbled through an avalanche, and triggered hundreds of creative chain reactions before reuniting in the finale. The build was led by Alexander Huang, San Jose local, leader of Reactica, two-time Guinness World Record holder, and producer of FOX’s “Domino Masters.” He was joined by an all-star team of domino and machine-building creators from across the country, including builders known for viral chain reactions, world-record domino projects, Rube Goldberg machines, large-scale kinetic art, and appearances on Fox’s DOMiNO MASTERS. “We’re so proud and grateful to continue to host this exceptional team of builders for The Tech Topple. It’s one of those magical events where engineering, creativity, and pure delight collide,” said Katrina Stevens, President &amp; CEO of The Tech Interactive. “Visitors get to witness the patience, testing, teamwork, and problem-solving behind a massive analog build, and then experience the thrill of watching it all come to life in one unforgettable chain reaction.” The Reactica build team spent the week in The Tech Interactive’s New Venture Hall designing, testing, troubleshooting, and rebuilding the complex setup while visitors watched and interacted with the builders during museum hours. The final topple was emceed by Matt Roben, The Kilted Auctioneer, who helped build suspense before a young visitor, selected by guessing the closest exact number of dominoes in the build, toppled the first domino. Tech Topple highlights The Tech Interactive’s commitment to hands-on, screen-free STEM experiences that show visitors how design, physics, engineering, and persistence come together in the real world. Every ramp, lever, domino line, ball track, and machine element had to work in sequence, turning thousands of individual pieces into one giant cause-and-effect adventure.
