The science of Hula-Hooping, as individual hoops or with a TON of hoops

Swiveling Science: Applying Physics to Hula-Hooping Have you ever wondered how Hula-Hoops work or what makes them able to spin around a person's waist or arm—seeming to defy gravity? The answer can be explained by physics, which can help you determine what makes an effective Hula-Hoop. In this activity you'll get to create your own Hula-Hoops and investigate how their weights affect how they spin. Which do you think will spin better, a heavy hoop or a lighter one? Get ready to do some hula-hooping to find out! Got it? Good. Now try it with 300 Hula-Hoops. It's almost impossible (Wired), but not quite, if you're as good as Marawa Ibrahim—aka Marawa the Amazing.

What if you tire before it’s through?

You have to use commercially available hoops, and it's quite possible that they could become lighter and thinner-- that would lead to higher records.

The lighter ones are also harder to control, though.

Marawa is an amazing woman! Also quite good at roller skating, and roller skating + hooping together. Plus...roller skating in high heels while hooping.
