Everyone loves soap bubbles. Most of us really love them. Particularly when they’re huge hovering things, hanging in the air or floating gently away.
Making large bubbles is easier than you might think. People argue endlessly over different soap mixtures (they’re a classic subject of after-dinner
arguments conversation for science communicators), but standard household washing-up liquid is almost as good as even the finest formulations. The real trick is in the way you blow bubbles, as this film will show you.
This is another film from the Royal Institution’s ExpeRimental series, all of which are worth checking out.
We’ve written up an entire page about bubbles, including a beautiful way of viewing soap film colours.
