Read moreabout the condition   200 Gram White Weather Balloon This is a new and unopened 200 gram weather balloon.  It is double sealed in an airtight package.  That is it's sealed within a plastic bag and then that bag is sealed inside another bag.  I assume that's to prevent it from being aged by the air.  It was manufactured in July of 2013.  It expired in July of 2015.  Though they have officially expired there is still plenty of life in these balloons.  It is in perfect condition. It is natural latex color.  When it's inflated it's a pearly white.  Uninflated it's roughly oval shaped and measures about 20 inches across and 30 inches tall.  It was manufactured by Kaymont Consolidated Industries. This balloon, as all weather balloons, are delicate. It has nothing to do with the age and everything to do with the material. Like all balloons the more it's filled the more delicate it becomes. If it's filled to 4 - 4 1/2 feet it has taken shape and is rather flexible and forgiving. It can be filled to 6-7 feet but it is much more sensitive and likely to pop. Note if it hits a tree it will almost surely pop. Things like grass and debris on the ground can destroy it as well. I've inflated several weather balloons of various sizes and it's always best to have at least two people. One to hold the balloon and one to manage the filling process. Also, if you're interested in high altitude experimentation please understand that as the balloon rises it will expand. You only want to fill it enough to get a good lift on your payload. These balloons were designed for single use, but if you're very careful I suspect it could be reused.
