If you've spent any time in public restrooms over the last few decades, you're probably accustomed to using one of these to "dry" your hands:
Unfortunately, they don't actually dispense bacon, but instead a gentle puff of lukewarm air that seems to take approximately 1.5 hours to work. Someone physically blowing on your hands would be more effective.
So, needless to say, hand washers everywhere were pretty psyched when these guys started popping up in public restrooms around the world:
If you've ever used one of these fancy high-speed hand dryers, like the Dyson Airblade, you know how satisfying it feels to have the water evaporate from your hands in seconds, like magic.
But it turns out, like so many seemingly perfect things in this tricky minefield we call life, these high-speed hand dryers are too good to be true.
A U.K. study found that using a "jet-air dryer" can spread 60 times more bacteria than an old-fashioned slow-speed hand dryer, and 1,300 times more bacteria than paper towels. Despite what the above gif would have to believe, this is not "hygienic" in any way, shape or form.
