is the float ball supposed to be empty or have sand in it to weight it down?

The float needs to float so don't weigh it down. As the float rises with the water level it engages a switch which turns the pump on. My pump sits in a 5 gallon bucket (in a hole) with many 1/2 inch holes drilled into it to allow the water in. I place 2 bricks on the bottom of the bucket then the pump on top of the bricks. The bricks help to keep debris from entering the pump. Keep in mind that this pump "lives" under water. I suggest an anti siphon valve (5 dollars) so once the pump is done pumping the water does not flow back into the hole......hope this helps.

It's a float, but may hold a small amount of sand to create the proper up and down motion to activate the switch.

Correct, there is no bounce to this ball. I prefer it though. I like the soft, sandy feel.

I agree with other responses. Empty, I can pick it up with one or two fingers. Full and it is anybody's guess. Luckily it has handles and wheels so you don't have to pick it up very often to move it around.

The bottom section is weighted with either water (which we use) or sand. It works very well and our family has enjoyed it for two years.

It is not noticable. Empty is about a pound or less. With it filled with water it pretty heavy.

Correct, the bags are empty. Sand from your local beach works well, but messy. I would not recommend Olympic weights... It rips the bag.

Honestly, it's not worth it to put sand in. We filled ours with water and it floats just a little. As soon as you step on it, the ladder goes down.

You have to fill it up yourself with either water or sand I believe - it was purchased for my daughter.

Yes. There are pockets that are made to be filled with sand (or whatever is available) to weigh it down and keep it in place.

Sand will make it heavier....with water, it moves around a bit when i punch it. but sand should make it a lot tuffer to push around...Also i believe emptying the sand off the base is going to be tuffer than emptying water off the base....

You have to fill it with sand, water or other material. I chose water. It is adjustable in height, I don't know the exact measurements but it is low enough for my 8 year old to pound away as well as myself who is 5'9". It does move when hit so you do have to kind of chase it, but I just figure it is an added bonus of cardio, who wants to stand in the same spot the whole time.

Hi, I don't have my box anymore but ours just floats the way it is. My husband noticed that there is styrofoam on the under side of the rim that we think makes it float. I think it came that way though. I hope that helps.

The float is very light because it's made of a rubber/foam material... maybe a pound. The device is worn on the back.. connecting in the front. It helps to keep the child tilted slightly forward to assist with swim motions of arms and legs. I highly, highly recommend this product. It has done wonders for us.

I would say that ball has a leak....NOT NORMAL...You should notify the shipper! There was no sand in my box

The float is light. Yes, I would recommend an air pump to inflate. It is a bit much to inflate manually for me.

Not sure of the actual weights but the ball is too heavy to try to roll it along the sand. You have to heave it. The pins appear the same as regular ones. Game was a lot of fun. Well worth purchasing v

The balls are round with weights on the inside and black foam on the outside; they roll straight, not wobbly. The pins stand straight and are slightly weighted at the bottom to hold them up. They are well-designed to work in conjunction with the ball to fall when knocked. We love this set and play it often! Hope this is helpful. Gretchen M.
