Question by VanHallyn: How high in the sky can unpowered aerostat balloons go?
I just saw a video with a camera attached to a small aerostat balloon and it looks like it went incredibly high. Copy and past the link below to another window to see the video. I want to know if it really goes that high, or if it is special effects. I know nothing about these kinds of things.
Answer by Austin Sorvala
As the balloon rises into the atmosphere the atmospheric pressure on the balloon is less allowing the balloon to expand…the balloon will continue to rise and expand until it finally reaches the max size the balloon will expand then it will burst…if you were able to get a balloon that will continue to expand it would float to the “top” of the atmosphere…in this specific cases the balloon used can expand until it is almost 20 feet across!…Which allowed it to go incredibly high.
