Electricity Gives Bubbles Super Strength 66

Posted by samzenpus
from the under-the-bubble dept.
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."

    Someone want to translate this cryptic passage to English?

    The irony is that it is in English.

    What you want is a translation to American.

    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.

Don't be irreplaceable, if you can't be replaced, you can't be promoted.
