I watched this last night. I found it absolutely fascinating, especially the medical application of micro bubbles as mini syringes for targeted drug delivery.

Physicist Dr Helen Czerski takes us on an amazing journey into the science of bubbles. Bubbles may seem to be just fun toys, but they are also powerful tools that push back the boundaries of science.
The soap bubble with its delicate, fragile skin tells us about how nature works on scales as large as a solar system and as small as a single wavelength of light. Then there are underwater bubbles, which matter because they are part of how the planet works. Out at sea, breaking waves generate huge plumes of bubbles which help the oceans breathe.
From the way animals behave to the way drinks taste, Dr Czerski shows how bubbles affect our world in all sorts of unexpected ways. Whether it's the future of ship design or innovative new forms of medical treatment, bubbles play a vital role
