    Balloon Hovercraft

    Yes, I think it will work with the bottle cap, but with some modifications. First, I suggest you flip the cap upside down so the smooth side is against the ground/table. I would also suggest taking a soda bottle cap and use a nail to punch a hole in the top. Then, punch a matching hole on the sports bottle cap. Finally, hot glue (or superglue) them together. This way, the balloon nozzle could go over the soda bottle cap (you way want to tape the balloon in place depending on the size of the nozzle), but the air blows out under the sports bottle cap.Or, maybe I'm misunderstanding and you are asking if you can use a sports bottle cap attached to a CD?

But, make sure you can stretch the balloon nozzle over the cap. The great thing about the spool was it had a built-in hole and a nice fit for the balloon. I didn't build a prototype, but in my head in seems like either will work. Good luck! I'd love to see the final result!
