If you don’t need handles just go to Target or Walmart and buy some cheap rubber balls in the toys section. Let the air out and fill them with water. Diffent sizes = different weight.
To fill with water easily go to a hardware store.
In the lawn care section they should have water hose repair kits. Buy one that will tread on to your hose and has a small nipple.
Then go over the air tool/compessor acessories. Get a needle for an air hose that is used to fill up basket balls, ect. Glue the air needle into the hose fitting. Attach to hose, insert needle into deflated ball and fill with water. I guess you could put this inside a canvas bag as well. I just carry a large one around the yard and curse at it.
Also useful in making medicine balls out of basketballs, soccer balls, etc.[/quote]
