I posted a while back about a ball pit I’d installed in my room. Everything in that post was true, but the pictures were a little misleading.

Looking at that, you don’t necessarily realize how cramped those people are. I framed the pictures to make it look larger than it actually was (THAT’S WHAT SHE SAID). In fact, the ball pit was only about the size of a large bathtub or small jacuzzi. In the pictures on the site, it was barely deep enough to be buried in, and when we shrunk the area to make it deeper, it was barely big enough for two people.
When people came in and saw it, they were always startled at how small it was (also what she said). There was no room for hide and seek, and barely even space for surreptitious ball-pit groping. This was a terrible state of affairs. It was nice to sit in, but really, why bother having a ball pit if we were gonna do such a half-assed job of it?
Well, as of this week, the situation has been rectified.

We all chipped in and quintupled the volume of the ball pit. It’s now set up opposite a hacked-together server-projector system (yes, that means Guitar Hero in the ball pit — that’s a controller you see on the left). It’s lined with blankets and foam padding, and is oh so comfortable. We’ve had two people fall asleep in it already.
For sanitary reasons, we of course have a few rules:

It’s still only half the size of the recently-constructed Last.fm ballpit. But it’s finally big enough to really hide in, stretch out, and grab someone’s ass without them being sure who did it.
On the other hand, it has the slightly unnerving effect that we now have no idea how many people are in the apartment at any given time.
For science, the next experiment will be “what do cats think of ball pits?”

They are held together by many zip ties at each joint, and overall it’s very sturdy (after a couple initial blunders). They’re anchored to the walls by rope — I drilled some blocks into the baseboard with pegs to hook onto.

You’re not gonna get cheaper than 10 cents per ball, as far as I can tell, and I don’t really know who the best suppliers are. eBay is no good — you need at least 1,000-2,000 for a ball pit that’s worth anything. I recommend calling toy stores and places that might have ball pits and asking them to forward you. I got mine from TinkerTots, because they had a decent deal on crush-proof balls, which were strongly recommended to me (you can jump around in the pit and not worry about them). But they cost more.

When I was a kid I used to always imagine living in a house that had a room that was filled with water. There was a little door you could crawl through way up high, and only a few feet of space between the water and the ceiling so you could breathe.
Also, one of the rooms’ floors was entirely made out of mattress. It was a Bed Room.
Please make these happen too. 😀

I fell asleep in our ballpit after the epic “clean-up” operation.
I woke up freezing and partially asphyxiated. The balls apparently don’t insulate heat and also are somewhat too packed for adequate carbon dioxide dissipation.
Conclusion: not recommended!

Hey, I noticed above that you stated “you need 1,000-2,000 balls for the pit to be worth anything”…how many balls does the pit you have now have in it? Was the 1,000-2,000 ball number for the first iteration of said pit, or this new one?
Great idea, something I’m going to look into installing in my apartment one of these days…

If it makes you feel any better, I doubt this is a “do it for one year and leave it” sort of thing. While I can’t speak for the XKCD crew, I was thinking it would be fun to have in my apartment, then when I (someday) have kids they could have a blast with it. As long as the balls are usable, they will be used. Trust me, if a geek invests in a ball pit, it will get more than it’s fair share of use…Here’s to hoping it really will be here forever…
