1. Put your car on a flat and smooth surface
2. Blow up the balloon and twist it so air doesn't come out
3. Attach, tape, or glue, however your car is made, to your car
4. When it's ready let the balloon go and watch it go
Sorry if it didn't help, I'm making a one now and can't get it to move but I know how it works (kinda).

A balloon car works by your air because you have to blow up a balloon and put it on the end of your boat.
