A good friend of mines Dad passed away last week...((( Moment of silence ))) At the end of the funneral at the grave side they released a bunch of Balloons .At the dinner that followed some of us were talking about where they would end up .There wasnt any wind at all that day so they climbed almost straight up in a hurry and kept climbing out of sight .I guess all of us were wondering how far a normal Helium ballon can climb (( Is there a ceiling where it wont rise any further .)) Some thought with thinner air it might expand and pop if it got to high . How many miles could one go ??
Any body have any knowledge or thoughts on this ?????
