@chemteacherphil: Rusting is considered a destructive chemical process, and the rusting of vehicles accounts for $3 billion dollars in related repairs in the US annually! But, that process can actually be used to keep you warm in the winter months! When iron rusts, it combines with oxygen in the air, forming iron (III) oxide, the orange crumbly solid that we know as rust. This process also is exothermic, meaning it releases heat to the environment. So, I decided to use the rusting of steel wool to create a homemade handwarmer! Steel wool works well as it has a large surface area, so it can react rapidly with oxygen in the air to generate heat. #chemistry #chemteacherphil #STEM #STEMTok

One of my favourites is using the vinegar rust solution (vinegaroon) on veg tan leather, and watching the natural reactions with the tannins

are you sure the iron isn't just reacting with the vinegar instead of the air?

When I first saw your videos, I was a freshman in high school. Now I am going into my top university. I hope university chemistry will still be as fun

So like in American, how hot is that?

If you let it melt into the vinegar, you use it to turn veg tan leather black.

if you take it out of the vinegar and rub it over wood, the wood will turn black

what difference between iron oxide from reaction with oxygen in air and iron oxide from burning in oxygen

it never occurred to me that steel wool was actual steel lol. I just thought it looked like steel, therefore, steel wool
