Have you ever been at the beach and seen a banner streaming behind an airplane? Maybe it says something like "Grab a Hot Dog at Captain Jack's" and you think "Hey a hot dog would be good." That's the power of advertising and we see it everywhere — on TV, social media feeds, in magazines. Advertising is a big business. But does it make sense to spend the money on flying a banner over a crowded beach or writing something in the sky? What do you really know about aerial advertisement? How big does something need to be to see it from the ground and how do you write in the sky? We'll explore those topics and more in this episode of STEM in 30.

The episode of our educational webcast series STEM in 30 will premiere on the National Air and Space Museum YouTube channel on March 9, 2023.

This program is made possible through the generous support of Hexcel.
