Hover Craft Inspired Spin Top

I had this idea of making a hover craft that could be propelled by balloons, but that idea didn't work because balloons weren't powerful enough to keep the propellers going. The whole thing ended up spinning on the table rather than hovering in the air, which led me to turn it into a spin top that would keep on going and going if you pump air towards either the propellers themselves, or into the opening duct in the centre of the thing. It'll speed up and keep spinning until you want it to stop!
