how many ball would you need to fill the pool half way? (to use as a ball pit)

OK let's do some math. Let me put on my nerd glasses. The pool has a 33" radius, and half way would be 8" deep. So, the volume is pi*(33^2)*8 = 27,369 cubic inches. Based on sphere packing mathematics, roughly 64% of this volume will be filled by the volume of the balls. Lets say that the balls are about the size of the tennis ball, which has a volume of 8.2 cubic inches. So you take 27,369 x 0.64 / 8.2 and the result is 2,136 balls.

We started with 200 and they barely covered the bottom. Ended up with 800! Well worth it though. That was 6 years ago and our boys still use it and every friend that comes over goes straight for it. Now that they are older we do have to replace the pool about 2x year, but I stick with this one. It holds up gear.

We spread about 10 bags of play sand underneath the pool every year to keep things level and keep small rocks from breaking through (once filled the pool is heavy!). Hope this helps!

First, find the volume of the pool. Multiply the inside diameter, (distance across at the center), by how deep the pool is, and then by pi, (3.14159). Next, find the volume of a ball. Take the outside diameter of a ball, multiply it by 2 and then by pi. Then divide the pool volume number by the ball volume number. The answer will be a close guess of how many balls you will need. It is a guess, because there will be spaces that cannot be filled, so you will have a few extra balls left over.

Thank you. I thought I read you use 20% less of this then sand. Our pool is 23,000 gallons, so I thought we would need 5 bags.

My best estimate would be around 200 assuming the balls are about 2" in diameter, but I am just guessing.

One container/jar of sand is enough for it. They need to make bigger sand boxes! Easier to control kids with this size, though.

I got this to use as a ball pit at the birthday party when my son turned one. The one year old babies played in it at the same time with it full of balls, no problem. I hope this helps

In my opinion this would work well as a ball pool. I am unsure about using a float in it because it is not very deep.

10 50lb bags of play sand was enough to fill it 3/4 of the way. The directions say it can hold 17 bags and I'm assuming that amount would fill it very close to the top.

I would say at least 2 or 3, maybe more, its a little bigger then on ogf those kiddy pools

150, sounds like enough, but we had to by a second bag to get the ball pool to where we wanted.

We used 12 5-Gallon buckets and there was still plenty of room. I think in the description or one of the reviews it recommends a certain amount of sand.

I use these for a giant kurplunk game, but I have fall into a small plastic pool. One bag is about 1/3 maybe of that. My one year old niece loved it and it was just about right for her. So depending on how small the pool is. I'd suggest 2, if your wanting it full.

In my opinion for a playpen, 200 would be enough for a 1-3yr old. However, to make it more fun and really fill up the playpen, I would maybe get two sets. The balls get tossed around and maybe a few misplaced. My son is obsessed with balls right now so balls get taken in the car, to the grandparents or left behind in the yard etc. We have only had 1 set and they are still enough for now and going strong. If we were to have another party I would order a 2nd set to really fill up my sons pool.

I believe I put around 150 balls in the top container on my Lobster. It is a great machine. Worth the money to get your skill level back up.

A filling hose from a helium tank is helpful. Depending on the size of your balloon, it may take 2-3 full size helium tanks to fill. Helium suppliers typically rent the tank; you just buy the helium.

I have a 14 x 36 pool and I used two cans and barely finished the pool, to be on the safe side three cans should do it with yours.
