i just got back from target, and they had rubber balls, 8.5 inches(21cm) in diameter, 2 for five dollars. i dont know how much they will end up being once filled with sand, but this seems like a great deal. they are the playground balls that have small dimples all over.

I filled a men's size basketball full of sand (very-fine for pool filters) and it was 20lbs. I am going to make the size you are talking about for training teenage boys, probably 12-16 lbs. hope this helps.

I got one of those very same playground balls, used it for a tornado ball, and even with the rope through it, it's only a couple pounds lighter than the basketball. The basketball may actually be closer to 24lb (I filled it tight), so the playground ball may be 20...

I got some of those a while back. I filled one with kitty litter (something I had handy) and water for extra weight.

I sealed the hole with a household rubber cement, but it started leaking. Good luck with your project!

Use plenty of duct tape! Trust me.

Finally got around to filling one ball with sand. Depending on what room of the house I weigh it in, it is between 16 and 19 pounds. no idea why I have different gravitational pulls in different rooms :-)

I also made the first of many mistakes. When filling it almost to capacity, lift it from the floor to put more in, or you get a small flat spot on the bottom, which prevents it from being totally packed. I discovered this after I wrapped it with duct tape. I figure maybe the slight space will give it more "play" and it won't break when I start tossing it.

Hank:

It will (eventually) break . . . but more duct tape fixes it.

A tornado ball is made the same way as the homemade medicine balls, but with a piece of rope going coing out of it. Here's a link:

Just knot a rope and sneak it inside, so the rope comes out and you use that as a handle.

You can find all kinds of exercises for them if you do a google search. Personally, I have not found much use for mine yet.
