The pathogenesis of ectopic gastric mucosa is a matter of debate between a congenital-embryological-and an acquired origin-consecutive to a gastroesophageal reflux (GER) like Barrett's esophagus -, the most commonly accepted theory being that these areas are embryological remnants.
Standard size latex filled helium balloons stay afloat for approx 8 - 12 hours, metallic helium filled balloons float for 2-5 days. I have found that a 36 latex helium filled balloon can stay afloat for a number of days due to the thickness of the balloon and the massive quantity of helium.
Report Abuse. I can't tell you the exact height... I'd imagine mile or a mile and a half. However, I can tell you that the balloon would pop when the air pressure outside the balloon would become too low to hold in the high air pressure inside the balloon.ow far does a helium balloon go in the sky when you let it go outside? I let two go today for my cousin who died and one for a kid who died in a car crash 2 weeks ago.
