"Using a variety of liquids, I tested their effect on steel wool using controlled conditions over one full week. I chose this experiment because it had easily controlled conditions, materials were easily accessible, and I would be able to monitor the experiment at all times. I used new mason jars sealed tightly to contain the water, lemon juice, cola, salt water, and water, and the steel wool all came from a single unopened package, ensuring that the experiment would take place in as tightly controlled conditions as possible. I hypothesized that the cola would cause the biggest reaction before the experiment, but the salt water turned out to cause the most rust. "
