How To Make a Beachball
- 1). Grip the trash bag so that the bag below your hand is approximately square.
- 2). Inflate the bag by blowing into it until the bag is tight, then gripping tightly to trap the air.
- 3). Spin the inflated portion of the bag several times, then tie off the bag at the point you were holding it.
- 4). Trim the excess bag from above the knot.
- 5). Wrap the bag with the duct tape, being sure to tuck in the corners to create a spherical shape, and to cover the entire exterior with tape.
- 6). Paint your ball with water-proof paint.
