Blowing into old game cartridges didn’t actually help at all!

If you’re old enough, you probably remember when you popped in a game into your game console only for the game not to boot up properly. You knew what to do right? Take it out, blow on it to get the dust out and put it back in, and it worked like magic.

Guess what? You were actually harming your game. Instead of blowing dust around, you were introducing moisture into the game and making it rust little by little. What actually helped was taking the game out and putting it back in. The reason games failed to boot was because the cartridge didn’t connect fully, and taking it in and out helped until you got the right position.

A guy ran an experiment to figure out the damage you made. Check it out here.
