Electricity Gives Bubbles Super Strength 66

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."

    The reference is to a British children's TV program called Blue Peter [wikipedia.org]. 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.
