When super-high tech hand dryers started to come to Ireland, we couldn't get over how cool they were.
They're environmentally friendly, hygienic AND they actually dry your hands properly? Hallelujah!

"This is the several strains of possible pathogenic fungi and bacteria that you’re swirling around your hands, and you think you’re walking out with clean hands. You’re welcome," said Nichole.
We're scarred for life.
