Wow mom, the beach looks great from here, let's go please!
Yeah, now I can play with my new cars!
But son, remember not to put them on the water!
Nooo, I don't understand what just happened. My cars are turning kind of yellow!
Don't tell me that you had them on the water!
Oh, TIMMY, come on, I just told you not to put them on the water... Pff I know what happened
I DON'T KNOW WHAT HAPPENED SORRY!
Look, what happened, is due to corrosion. It happens to iron and its alloys when it is exposed to air or water for a long time.
Oh, so thanks to the moisture in my cars they got like this, I saw that topic in my school!
Yeah, that's why cars are protected with paint and bicycle chains are covered with grease. Anyways, you get punished because of that... ONE WEEK WITHOUT TOYS!
Fine, I'll be more attentive with oxygen, water, and iron while playing with my cars...
