What happens when a Brownie Troop goes to a weather balloon launch? One Brownie guesses that they\u2019ll make contact with unicorns in the sky. Atmospheric scientist Gary Morris shows us what it takes to launch the biggest balloon you\u2019ve ever seen to the very top of Earth\u2019s atmosphere. Along the way, we\u2019ll learn why weather balloons are the best way to find out about air pollution. And who knows? Maybe we\u2019ll discover unicorns, too!\n\nThis story came together when a Brownie troop leader emailed Tumble to see if we could do an activity with the girls.
