When you think of conference rooms, things that come to mind may include…
- tedious, seemingly never-ending meetings
- monotonous, tiresome speakers
- powerpoint presentations with 100+ slides on the state of your company’s financials
But today’s Office Hack turns that place of dread into a place of play. Employees at Mozilla, makers of Firefox, dumped tens of thousands of rubber balls where you would expect to find a boardroom table.

Listen to this story on our Office Hacks podcast.
The Mozilla conference-room-turned-ball-pit isn’t just for frolic, fun and body-rolling, it’s also for conducting serious business. At least, that’s what the people at Mozilla said.
The room has video-conferencing capabilities and there is a couch for, you know, serious meetings.

The ball pit happened quite by accident. Someone brought in a bag of rubber balls to prank a colleague, but when the prank fell through, people got to wondering how many more balls it would take to fill part of a conference room.
“One day we came into the office, and there were twenty-thousand ball pit balls in pallet sized boxes stacked up outside that room, and they were building a Lego retaining wall to hold it all together.” Potch, Developer Relations at Mozilla

The Mozilla team quickly realized they would need to set some ground rules. The laws of the pit are as follows:
- No shoes
- No diving
- No high jumping
- And no peeing (!)

There have been a few ball pit mishaps, like the time all staff were set on high alert for the missing ninja, lost somewhere in the depths of balls.
But mostly, the ball pit is just for serious business. At least that’s what the people at Mozilla said.
