In May 2025, an American man and woman met a big black balloon on their way to drive. 
         Yes, a big balloon. But before any clarification, I still don't think this is a balloon. For doubts about whether it is a UFO? Here are two questions. 
         First, whether it is an ordinary balloon or a weather balloon, what does it rely on to fly? The weather in this video is not so good, but rather bad. 
        Second, how heavy is it? Why is it easy to fly in the sky, but the moment it falls on the snow, it collapses smoothly in the snow pile.      
        You can carefully watch the moment it lands. This is obviously not a normal force! So what do you think?
