A neat little chemistry trick that makes steel rust within seconds.
Yes, this chemistry trick makes steel rust. Steel wool is made of not only iron but a mixture of iron and carbon.
To prove that this is actually steel watch my video where I burn steel wool (after the iron is burned, carbon is left behind. https://www.youtube.com/watch?v=pBuqGALPBSI
Things you need:
Hydrogen Peroxide ( 3%)
(You can use paper clips but it takes 5 minutes to rust)
Note: Though the solution isn’t dangerous, don’t touch it because it may cause skin irritation. Wear gloves and googles as always.
Note: There is a typo in the video:
The steel wool is not oxidising the iron, the peracetic acid is.
