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.
