    My understanding of the Dyson thing is that instead of washing their hands before putting them in the dryer, the experimenters put on soiled rubber gloves. Unsurprisingly, a dryer designed to rapidly remove water also rapidly removes dirt.

    So, the take away message is, wash your hands properly!

    Yes — but I think the problem is that it pushes them out into the air, where they linger for many minutes afterwards — so if I enter a bathroom after someone who hasn’t done a particularly good job of washing their hands before drying, I’ll get a faceful ;)
