Today I learned about how hot air rises. One thing I learned is that the molecules in the balloon have to spread a part for the balloon to rise. I also learned that the more passengers there are, the more hot air you have to use. Did you know that you can’t steer a hot air balloon? You have to let the wind take you some where. There’s a velcro hole at the top of the balloon that is connected to a rope and when you pull it the hot air leaves the balloon and the balloon sinks to the ground That’s what I learned about a hot air balloon.
