About this episode
Have you ever accidentally let go of a helium balloon and watched it float up … up … and away? It drifts way up in the sky until it’s just a tiny speck! But what would happen if a balloon made it all the way to outer space? We asked astrophysicist Amanda Farah to help us find the answer. Got a question that popped into your head? Send it to us at BrainsOn.org/contact , and we’ll float you an answer! See omnystudio.com/listener for privacy information.
