====Summary====                   
{{$demo.summary}}



====Procedure====  
  - Crack an egg into a small glass bowl (scramble if desired).  
  - Gently pour 70% rubbing alcohol (isopropanol) or high-proof ethanol over the egg.  
  - Swirl gently and observe the changes.  
  - After 5–10 seconds, the egg white should begin turning white.  
  - Leave for about 15 minutes; maximum coagulation will occur.

====Variations====
  * Test other conditions such as high salt, acidic (vinegar), or alkaline (baking soda solution) environments to see if proteins also denature.  
  * Compare the results of heat-cooked eggs with chemically “cooked” eggs.  
  * Try different concentrations of alcohol and record how quickly coagulation occurs.



====Safety Precautions====
  * Do not eat the alcohol treated egg - rubbing alcohol is toxic and even ethanol treated eggs are unsafe to consume.  
  * Perform the experiment in a ventilated area to avoid inhaling alcohol fumes.  
  * Handle glassware and liquids carefully to avoid spills or breakage.  
  * Wash hands thoroughly after the experiment.




====Questions to Consider====
  * What changes did you observe in the egg white after adding alcohol? (It turned from clear and runny to opaque and solid.)  
  * How does alcohol cause denaturation? (It disrupts hydrogen bonds and interferes with the protein’s hydrophobic core, causing the protein to unfold and tangle.)  
  * Why is this process similar to heat cooking? (Both methods disrupt the weak bonds holding protein structure, leading to coagulation.)  
  * What other conditions can denature proteins? (High salt, extreme pH, or other organic solvents.)
