1. **Identify the hazard:**  
   A grease fire is dangerous because the grease is at a high temperature and can quickly spread. It is important to stop the flow of oxygen to the fire.

2. **Eliminate unsafe methods:**  
   - Using **water** is dangerous because water and hot oil can cause violent splattering and spread the fire.  
   - A **towel** can also catch fire or may not effectively cut off the oxygen without its own hazards.

3. **Determine the safe method:**  
   The recommended method for a grease fire is to cover the pan with a **metal lid or a cookie sheet**. This works by smothering the fire, which stops the flow of oxygen. When you cover the pan with a cookie sheet, you effectively block the oxygen supply, causing the fire to die out.

4. **Express the reasoning mathematically (conceptually):**  
   Let $$ F $$ represent the fire and $$ O $$ represent oxygen. The fire continues as long as there is oxygen, or  
   $$
   F \propto O.
   $$  
   When you cover the pan, you reduce $$ O $$ such that  
   $$
   O \approx 0,
   $$  
   which then leads to  
   $$
   F \rightarrow 0.
   $$

Thus, the correct answer is: **cookie sheet**.
Use a cookie sheet to put out a grease fire in a pan.
