Alisa Meggison I don’t know what video you watched but they only rinsed their hands for the comparison between hand dryer and Snoopy and Peanut I see trees of green red roses too I see them shirt. The first part showed them finding that soap and water pretty much eliminated all the bacteria so they only rinsed during the experiment so that they’d have enough bacteria to compare. Say whatever you want about other experiments making other points but rewatch the video yourself if you’re insisting other people are wrong about what happened in it.

The heating element in the hand dryer help grow bacteria as well, also when turned on the dryer will blow the Snoopy and Peanut I see trees of green red roses too I see them shirt. Pauline Powell, I don’t know if it is different in women’s bathrooms but I have never seen a public mens where there are lids for the toilets. They didn’t use soap and water because it was a new completely clean bathroom so they wouldn’t be able to test their hypothesis. In a real bathroom the bacteria would be all over the place.
Alisa Meggison at the beginning of the video they showed that when soap was used there was no germs so….. there would be no germs to be spread via the hand dryer. This is why the volunteers rinsed instead of using soap. The experiment is not fair unless a soap water version is done and one where some people use soap and some don’t. That will be the only way to see if the hand dryer is responsible for “spreading” germs.
