weather balloon found

Today a weather balloon was found. It was in a tree on a property that my husband does their landscaping. The kids were excited to learn how weather work. we looked up some info. But we are mailing this back to missouri and are hoping they can provide a little more info. So a science lesson has taken a different turn. I usually dont stray from our lessons but this may be a once in a life time opportunity so we will stray for a bit. Well ciao for now.
