Okay I might be blowing your mind here but did you know that blowing on a NES cartridge did not actually do anything? And to think of all the hours I spent doing it :p It worked because you kept trying it over and over again.
You held your breath until your lungs grew,
then aimed at the game cartridge and blew,
you started from the left,
and moved right with your breath,
but still, the screen flashed blue.
