Are you a maker? I am.
Our first project at the MakerSpace Workshop at DHF was a CD Hover Craft.
Our materials included a hot glue gun, glue sticks, a cd, a balloon, and a pull top bottle lid. I started by gluing the bottle top to the CD around the hole in the CD. Once that was secure and cooled I placed a balloon over the pull top on the CD and proceeded to blow air into the balloon. I hit a little snag. My balloon would not hold air long enough to hover. I decided to add more glue around the lid and the cd. I blew the balloon again and blew out the glue that had not totally cooled. Another air leak! :) I reglued and waited for it to cool this time. Success!
