The Tech Topple: The Largest Live Domino Build in California at The Tech Interactive

Get ready for the ultimate chain reaction! Tech Topple: The Great Adventure brings its massive, 40,000-domino spectacle back to The Tech Interactive for its 11th year. This year's jaw-dropping build features an intricate "one-ball path" where a single, determined ball will travel all the way from start to finish, triggering approximately 300 incredible chain reactions across land, sea, and sky-high surprises! Watch as the ball crosses an ocean on a ship, scales a mountain, and falls in an avalanche.

The entire layout is engineered by Reactica, a team of seasoned domino and chain-reaction artists who have built for brands like Disney World and the Golden State Warriors, with several members having starred on FOX's Domino Masters.

Want a sneak peek before the big drop? Come watch the builders in action and meet the team during standard museum hours on Sunday, July 12, and from Wednesday, July 15 to Friday, July 17!

Beyond the big crash, the entire museum is open for exploration. Visitors can become domino masters themselves by heading into the Tech Studio for interactive domino building challenges. It is a full day of physics, patience, and hands-on experimentation perfect for curious minds.
