I blow on the top of soda cans before opening them.
When I was very young I’d ride to and from school and it took me past my grandparents. During summer I’d stop in on the way home to grab a soda and because they kept them in a shed out back they’d get dusty before getting put in the fridge. So I’d blow the dust off and make sure the top is clean, fast forward 25 years and I still do it.
