Ball Case

The ball that carries objects. Easy to make if ya got the supplies. You'll need a knife, ball, duct tape, whatever u want to put in side, and a bicycle pump.
Make an Incision

Use a knife to make a cut in the ball. The length of the cut varies to the size of the object put in side.
Put an Object Inside

Take the ball and put an object into the incision.
Duct Tape Over the Incision

Take the ball and put duct tape over the incision. Glue may work but I didn't try it.
Blow Up the Ball
Blow up the ball to its normal size.
Peel Off the Duct Tape
Peel if the duct tape and take out the object(s).
