  1. Decorate the CD as desired.
  2. Cover the hole in the cd with a piece of packing tape.
  3. Poke small holes in the tape with a pin (this controls the airflow).
  4. Hot glue a pop-top soap cap or water bottle cap to the center of the CD or DVD disc.
  5. Be sure to create a good seal to keep air from escaping.
  6. Blow up a balloon all the way and pinch the neck to keep the air inside (don’t tie it).
  7. Make sure the pop-top is closed and fit the neck of the balloon over the pop-up portion of the cap.
  8. Place on a smooth surface and pop the top open.
  9. Begin hovering.
