How hula hoops stay aloft

Science Sessions are brief conversations with cutting-edge researchers, National Academy members, and policymakers as they discuss topics relevant to today's scientific community. Learn the behind-the-scenes story of work published in the Proceedings of the National Academy of Sciences (PNAS), plus a broad range of scientific news about discoveries that affect the world around us.

In this episode, Olivia Pomerenk reveals the physics of hula hooping.

In this episode, we cover:
•[00:00] Introduction
•[00:49] Applied mathematician Olivia Pomerenk talks about the history of hula hooping.
•[01:52] Pomerenk explains the fascinating nature of hula hoop motion as well as her own personal experiences with the children's toy.
•[02:44] She describes the experimental setup with robotic hula hoopers, as well as the mathematical model that arose from experiments.
•[04:44] Pomerenk enumerates the forces needed for successful hula hooping.
•[05:51] She explains how body shape affects hula hooping.
•[07:17] She explores potential applications of the findings.
•[08:01] Pomerenk discusses the caveats and limitations of the study.
•[08:44] Conclusion.
