The planet Mars takes its name from the Roman god of war.
It is roughly half the size of Earth and is the most explored planet in the Solar System.
Mars is a dry, desolate planet covered in red dust. This dust is iron oxide, also known as rust. The metallic rocks on Mars are literally rusting.
This rust can be whipped up into violent dust storms which can blanket almost the entire planet in a matter of days.
• White vinegar
• Steel disc
A steel metal disc was placed in water with a drop of white vinegar.
The acid in the vinegar rapidly speeds up the rusting process.
Filmed at 1 frame every 5 minutes using a time lapse camera, the rusting process can been seen happening in a matter of seconds.
