San Jose's Tech invites the general public to observe 40,000 dominoes fall today at 1 p.m.

With just hours left before all of it collapses, Alex Huang of San Jose paused Friday to tour the 40,000-piece amusement park he and his team of eight construction employees have inbuilt the lobby of Tech Interactive.

Perhaps within the hope that there won't be an earthquake overnight.

Huang, a outstanding member of the domino and engineering community generally known as Flash Domino, was just 16 when he launched San Jose's first Tech Topple in 2016. Last yr's construction was a miniature city called Topple Town. It was built from 20,000 dominoes and took greater than five minutes to destroy.

This yr's theme is “Kinetic Carnival,” with chain response machines inspired by fairground games, bumper cars and even a Ferris wheel. There are twice as many dominoes as Topple Town. Nine construction employees joined Huang this week to construct the amusement park. Among them were skilled chain response artist Lyle Broughton and former domino world record holder Erez Klein.

The fall will happen at 1 p.m. sharp on Saturday at The Tech, 201 S. Market St., San Jose. Museum officials expect a big crowd and advise arriving early.
