  • According to the math, washing machines should take several hours to get your clothes clean, but in reality it only takes a single hour or less. Now, scientists have finally figured out how they truly work.

    It takes about 5 gallons to do a change of clothes. At least if you use a portable washing unit you can buy from Amazon.

        So here's a related question for physicists. How exactly is it possible for my top loading washing machine to turn every single item of clothing inside out via agitation alone? it happens every single time. seriously, after thousands of loads over decades it maybe hasn't occurred on a single piece a handful of times.

          One thing about the ultra fast turbo washing machines. Won't a water current that fast damage the fabric? Would it do damage to the clothing and wear down the fabric faster than it normally would? That would make people dispose clothes at faster rate which wouldn't be good for the planet either. More waste and more demand for fabric. Just a thought.

            So they figured out that running non soapy water over a soap filled shirt will clean it better than soapy water? That's extremely obvious. soap sticks to water and dirt. If the water is saturated with soap then there will be less available water molecules for the soap in the shirt to stick on to. Maybe next they'll figure out that more aggressive agitation rubs the soap deeper into the fibers *facepalm*

              a turbocharge washer will ruin almost all cloth you own…any normal washer can possible ruin your clothes anyway…

                  I thought it will be about Navier-Stokes, but this is fine too. There are plenty of things that work, such as Navier-Stokes, but we still have plenty of questions about them that are still unanswered.

                          If you ever washed your clothes by hand on a flat Rock bed, friction speed and water movement is essential in getting stains and dirt off.

                              If it's an electric field that does the trick, might it be possible to apply a voltage to help this process along? Or is it about the voltage outside the fibers vs inside in which case a macro-scale field wouldn't do much?

                                                I can't imagine that any sort of improvements born out of this information will be in many people's homes for at least another 20 years. Washing machines tend to be a rather long-term investment... unless more of them start blowing their lids off again, I suppose.

We also don't know how cars work either ffs.
