How to make your own medicine ball

Step 2 Fill the ball

-If you fill using my method, you can use a dowel or a broom handle or something to occasionally pack down the contents as you fill it.
-If you fill using the small hole/funnel method, I think the only thing that you can do to pack down the contents is occasionally shake the ball to make sure that everything settles.

To fill the ball, I used an empty drink pitcher to pour sand through the opening cut in the ball.

Using a bag of play sand purchased from Home Depot ($4), the ball ended up at just below 25 lbs.

Dry sand has a density of around 1600 kilogram/cubic meter
Wet packed sand around 2000 kg/cu.m.
Some lighter household materials that would work for this instructable are:
Coarse salt is around 800 kg/cu.m.
Fine salt is around 1200 kg/cu.m.
Granulated sugar is around 850 cu.m.

Or improvise for your contents!
Just remember, sand makes a pretty heavy medicine ball by itself!

I've found cutting the top of a soda/ water bottle works well as a funnel.
