By my rough calculations, it would take about 8500 balls to fill that room to a depth of 9". However, I assumed cubical packing, rather than hexagonal, so your actual number will probably be about 15% higher, so at least 10,000. Also, I don’t think 9" is nearly deep enough.
The room is 16 feet long by 11 feet wide, but you need a third dimension: how deep do you want the balls to be? When you open the door and step down into the room, how far up on your legs should the balls come?
I came up with about 8300 balls but that assumed it was a cube as well. I believe balls will take more because they aren’t a whole cube so a guess would be more like 10,000 balls.
Hmm… My budget allows for about 1/10th of that (I was planning at about 1,000 balls).
Are there other options to acquire a LOT of those fun balls? One that doesn’t require going through the mail? Like a somewhat local distributer? I assume McDonalds either makes their own or contracts it to one big company… so asking them probably wouldn’t be much help.
Good guess!
If you fill up to Rhubarb’s rough and ready 9" mark, you will need 10,563 balls if we are talking about the most efficient face-centered cubic packing (and if I didn’t flub the math). This particular type of sphere packing fills 74% of the available volume.
I think your best bet is to ask at the local McDonald’s, Chunkee Cheese, etc. Someone there has to have some idea what the name of their supplier is. It’s way to cool of an idea to let it go to waste.
You may also be able to reduce the size of the room a bit by building a simple box-like bench around the parameter of the room. This could provide loungeing space, room to set drinks, etc. and reduce the cost of filling the room.
even sven, I like your idea of the benches. I’ll look into it.
I’ll post links to a couple of pictures of the room whenever I can get the chance to give you guys an idea of the project. My digital camera died a while back so I’ll borrow a friend’s.
Hi xash, I e-mailed Tuba. It was a password thing and I don’t use my former e-mail address.
And gigi… I now have some terrible mental images… though with or without… Thinking about clown balls is a scary scary thing.
I’m still looking for any advice… I like the bench idea if the cost of the balls ends up being way too much.
I called a couple of McDonald’s with play places but they either didn’t know where to get them or they thought it was a prank call. Well… I would’ve thought the same if around 10 at night someone called with that question…
