Electricity Gives Bubbles Super Strength

sciencehabit writes "Left to its own devices, a bubble will weaken and pop as the fluid sandwiched between two thin layers of soap succumbs to gravity and drains toward the floor. But when researchers trapped a bubble between two platinum electrodes and cranked up the voltage, the fluid reversed direction and actually flowed up, against the force of gravity. The newly strong and stable bubbles could live for hours, and even visibly change colors as their walls grew fatter. Because soap film is naturally only nanometers thick, this whimsical experiment could help scientists create more efficient labs-on-chips, the mazes of nanotunnels that can diagnose disease based on the movements of a miniscule drop of blood."

    Some washing up liquid bottles, sticky back plastic and Sellotape, Blue Peter were way ahead of their time, they just omitted the platinum electrodes and high voltage!

      I thought about antigravity as well, though your reference is lost on me. I'm currently imagining Back to the Future II cars...with bubbles on the bottom. The world will be cleansed...by bubbles. Of course that means there will be people who instead of walking will take the aerobus, so there will need to be bubble shelters where people can avoid the bubbles while waiting for it. After all, who wants to walk into work with sticky clothing, hair, etc.?

      The reference is to a British children's TV program called Blue Peter. Many decades ago, when I watched it, it would frequently feature construction projects where required materials were almost always an empty washing-up liquid bottle, sellotape and sticky-backed plastic. The last one being hard to come by in Aucherterarder; the target audience was clearly city kids.

      The irony is that it is in English.

      sellotape and sticky-backed plastic

      They are the same thing; Sellotape is a brand, and couldn't be named on the BBC. The third item you're missing is toilet / kitchen rolls :)

      Brands can be, and often are, mentioned on the BBC, as a result there were frequent references to Sellotape. Sticky-backed plastic is different from Sellotape, it's a wider plastic roll, typically about 50cm (20") wide.

  8. Thin bubbles by mbone · · Score: 3, Insightful

    Normal soap bubbles are about 500 to 1000 nanometers thick - that's why you can see colors (iridescence) on the surface - it's from interference (diffraction) of light reflecting on the inside and outside of the bubble wall. These bubbles are, according to TOA, nanometers thick, which is very thin, at least compared to the soap bubbles we see.
