Any balloon that is filled with air is not floating. It can be floated with hydrogen or helium. The cost of hydrogen is lower, but it is dangerous to encounter fire. When charging hydrogen, keep away from the fire source. Helium is an inert gas. High cost, but very safe. 2. Due to different light, different shooting angles, and different monitors, it will cause slight chromatic aberration. Since the balloon is an artificial point, generally about 1% of the error, thank you for your consideration.
