At 100,000 feet, the air pressure is 1/100th of air pressure at sea level. So the initial volume of the balloon needs to hold 300 cubic feet for every 15 pounds of lift. To reach 100,000 feet, the balloon needs to expand 100 times in volume. Take the cube root of that to get the increase in diameter
To lift around 15 pounds takes 300 cubic feet of helium. You can scale it up from there. Don't forget that the balloon needs to increase its volume by a factor of 100.
I was wondering if some of the government balloons can actually break free of the earth's gravitational pull? I suspect not since at a certain altitude, the balloon weighs too much for any more lift.
what is the size of the first box and what is the type of computer, the operating system and camera being used here

What's the potential range for a free-falling balloon/remnants?

DO you know how high did the Balloon go

How big a balloon do you need to lift a person into near space?

yeah, otherwise it'd be like a piece of wood floating on water - then starting to fly up into the air!
helium balloons can float on-top of the atmosphere - they can't go any higher.
