A woman who was posing for a photo inside a Los Angeles gallery accidentally knocked over a pillar, sparking a domino effect that ruined an art installation reportedly worth as much as $200,000.

Moments before the excruciating incident took place, tourists can be seen in the security footage observing inside a room installed with dozens of pillars of various sizes lined up in four rows, with art pieces placed on top of them.

The room, created by artist Simon Birch, is called the Hypercaine, just one of the 14 rooms featured in the exhibit at The 14th Factory, Daily Mail reports.

In an apparent attempt to pose for a nice photograph, the unidentified woman appears to crouch down next to one of the pillars.

Disaster struck, however, when the pillar got toppled over, causing a chain reaction to the other pillars in the row which all came tumbling down in a domino effect.

A YouTuber, claiming to be a friend of Birch, uploaded the clip under the handle Party Pooper.

In the description, the uploader wrote:

“This took place at my mate Simon Birch’s art installation The 14th Factory in Los Angeles when a lady tried to crouch down and pose in front of a pillar holding a sculpture to take a picture. She accidentally leaned on it and the rest is history… $200,000 worth of art destroyed!”

In creating the entire exhibit, 16 interdisciplinary artists from China, Hong Kong, the U.S., the U.K., and Canada, reportedly helped Birch realize his vision.

According to Design Milk, the project took six years before it finally came to fruition. While he was initially planning to set it up in Hong Kong, where he is currently based, he later chose an empty warehouse in downtown L.A., instead.

Birch, a brain cancer survivor, facilitated the destruction of his most valuable possession: a $50,000 Ferrari 308 and included it as part of his art.

As for the woman who ruined the exhibit, it was not reported if she was penalized by the organizers.
