Why Blowing into Nintendo Cartridges Was a Bad Idea

It turns out blowing into your old Nintendo cartridges probably did more harm than good. The reason? Human breath is gross.

What's the Latest?

During the late 1980's and early 1990's, millions of 12-year-olds across the globe all somehow got the same bright idea while troubleshooting their Nintendo game systems. Just blow into the cartridge! Legions of kids did just that, concentrating gusts of breath into the exposed undersides of Super Mario Brothers 3, Chrono Trigger, and The Legend of Zelda. And for all we knew (I admit I was an ardent cartridge-blower), it totally worked. The toxic stuffs inhibiting our mindless fun would be expelled. We'd pop in the cartridge in, switch on the console, and marvel at the dust-free magic of 8-bit, 16-bit, and 64-bit paradise.

What's the Big Idea?

As you may have already seen via the above link, Chris Higgins of Mental Floss authored a fairly comprehensive history and analysis of cartridge-blowing back in 2012. He posited that the practice wasn't nearly as effective as our 12-year-old selves thought, that the supposed results were more accurately ascribed to chance and confirmation bias. Long story short: he was right. Blowing into the games' undersides likely did more harm than good because of the corrosive elements found in human breath. "Dust" was rarely, if ever, a factor in NES consoles not reading cartridges -- rather it was a matter of the 72 pin connectors in the system not matching up with their partners in the cartridge. Taking the cartridge out and putting it back in gave gamers another random chance to get all the pins to connect -- regardless of if blowing had taken place. Read Higgins' fascinating article to learn more about Zero Insertion Force, pin connectors, and the science behind cartridge-blowing (which I think needs a better moniker).

After death, you’re aware that you’ve died, say scientists

Surprising Science

Time of death is considered when a person has gone into cardiac arrest. This is the cessation of the electrical impulse that drive the heartbeat. As a result, the heart locks up. The moment the heart stops is considered time of death. But does death overtake our mind immediately afterward or does it slowly creep in?

Behold, the face of a Neolithic dog

He was a very good boy.

Historic Environment Scotland
Surprising Science
  • A forensic artist in Scotland has made a hyper realistic model of an ancient dog.
  • It was based on the skull of a dog dug up in Orkney, Scotland, which lived and died 4,000 years ago.
  • The model gives us a glimpse of some of the first dogs humans befriended.
