Corrosion Rate in Salt Water

So we have established that moisture on iron causes it to corrode in the rust video, but what about salty water? It is generally accepted that salt water causes rust to corrode quickly but why does this happen?

We put some steel wool to the test in different conditions:
1. Steel wool in air
2. Steel wool in oil
3. Steel wool in water
4. Steel wool in salt water (Sodium Chloride)
