What Things Rust Easy Science Experiment
In this fun and easy science experiment, we’re going to determine what things will rust when left in water.
- Several small paper cups
- Various metal objects like paper clips, coins, nails, safety pins, tacks, staples, keys, etc.
- Fill the cups halfway with water.
- Put one metal object in each cup.
- Check on the objects each day for ten days and document your observations.

How it Works:
Items that contain iron will rust as the iron begins to corrode. The surface of a piece of iron will corrode first in the presence of oxygen and water. After enough time, the iron will completely disintegrate and turn to dust.
Make This A Science Project:
Try adding salt or sugar to the water to see if it speeds up or slows down the rusting process. Try putting the items in vinegar. Try putting the cups containing the items in the refrigerator to see if the cooler temperature speeds up or slows down the rusting process.
