How to make an inverted bubble

How do you make an inverted bubble? Wait, what’s an inverted bubble? In this video, Steve Mould demonstrates how to make this movable hole in soap film with a large wire bubble blower (wrapped with soapy pipe cleaners), some good quality bubble soap, and a loop of thread. He explains:

It’s surprising when you first see and it’s fun to think about why it behaves the way it does. It’s also a useful metaphor for cell membranes so I explore that a little bit too.

Mould also shares three of his excellent hands-on science books for kids: The Bacteria Book: The Big World of Really Tiny Microbes, How to Be a Scientist, and Science is Magic: Amaze your Friends with Spectacular Science Experiments.
