Can a latex balloon or a bouquet of balloons make it into space? Or will it just pop in the atmosphere?

We saw a balloon bouquet going up in the air today and were wondering if the balloons would pop at a certain point in the atmosphere or would they continue on. I know nothing about the different atmosphereic levels and whether ballons would even stand a chance.

Can a latex balloon or a bouquet of balloons make it into space? Or will it just pop in the atmosphere?
A lighter than air balloon will rise as long as it is - lighter than air. Once it reaches a point where the air is thin and equals the air inside the balloon, it will stop rising. As it rises the air pressure lessens so it will expand. So the question is, which point will the balloon reach first, where it hovers stable or where it expands beyond what the material can hold and it pops? Into space..I dont think so
Reply:not to space itself but the edge os space certainly. but not your everyday party latex ballons, they are to thin and weak. but NASA in the early 60s did get a modified weather ballon with a basket underneath carrying a person (in a space suit due to lack of atmoshere) up to 110,000 feet. he was so high he could see the curveture of the earth. the first time any person saw with there own eyes that the earth is indeed round





now your everday ballon will expand and pop when it gets up to 30,000 feet, lower air pressure allows it to expand
Reply:Probably they will not pop, but they will only go up so high, and no higher as they loose buoyancy in the thinner air at high altitude. The balloons only float if they are lighter than the air around them, and the air around them gets lighter as it gets thinner at higher and higher altitude. Scientific research balloons are very light and very big to be able to go very high in very thin air, but party balloons are made of comparatively thick and heavy materials and so cannot go very high.
Reply:a latex balloon would pop when the pressure dropped to low and the internal pressure popped it. but if the material had sufficient tensile strength it would float up word till the weight of the air the balloon dis paced equaled the weight of the balloon and the gas it contains
Reply:They will probably pop before they reach 10,000 feet (that's a pretty low altitude). As they rise, the pressure on the outside drops because the air gets thinner. But the pressure on the inside stays the same. So the difference between the pressure on the inside and the pressure on the outside grows, and the balloon expands. These balloons are not very strong, and they are pretty full to start with, so it wouldn't take much to get them to fail.
Reply:Party balloons would reach a maximum altitude and stay there. The helium would leak out and they would then fall.





Weather balloons are designed to attain a maximum altitude then burst. They are a lot flimsier than party balloons to make this happen.





Any balloon will survive in space as long as the pressure difference between inside and outside doesn't exceed the structural strength of the balloon. See, for example, the experiments in inflatable modules for space stations, which are effectively balloons.
