Things You'll Need:
- Plastic bag
- Sand
- Several rolls of duct tape
-
Step 1
Fill the plastic bag with sand to the desired weight of your ball.
-
Step 2
Seal the bag, pressing as much air out before sealing as possible.
-
Step 3
Wrap the entire bag in a layer of duct tape by tearing off strips long enough to wrap around the entire circumference, and overlapping them slightly.
-
Step 4
Round out the shape of the weighted bag by adding more tape to areas that need to be padded out until the object is roughly in a round shape.
-
Step 5
Continue to build around the shape by tearing off 12-inch-long strips of duct tape and securing them, until your ball reaches the desired diameter. The larger your ball is, the more smooth you will be able to make it.
