This ball can be used as a super-light volleyball, playground ball, or just a ball to play catch with. You might find other uses as well. The ball is light and grippy. It's cheap and easy to make. It is surprisingly durable and stands up to repeated kicking.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Gather your materials. You will need 2 12" balloons, a roll of duct tape, and, if desired, a different colored roll of duct tape for decoration (not shown). We used 2 balloons, one inside the other, for extra support and strength.
Turn one of the balloons inside-out. I discovered that the the inside of the balloon is dustier and less grippy.
Twist the balloon you turned inside-out like shown. make sure the balloon has no air inside.
Insert the twisted balloon into the other balloon.
Fold the top of the inner balloon onto the outer balloon, like shown.
Blow up the inner balloon and tie a knot on the top.
Start covering the balloon in duct tape. Be sure to pull it especially tight over the knot. If you put all the duct tape on tightly enough, the ball will be round.
Congratulations! You have completed your duct tape ball!
Step 9: OPTIONAL STEP
Decorate the ball with another color of duct tape.
