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



====Procedure====  
  - Take a raw egg while scuba diving or during a controlled underwater demonstration.  
  - Crack the egg shell open at depth (such as 60 feet underwater).  
  - Observe how the egg white and yolk remain together in a floating mass instead of dispersing.  
  - Move your hand or finger near the egg to see how it behaves like a jellyfish in water.  
  - Optionally, clap hands or disturb the egg to see it break apart into pieces.

====Variations====
  * Perform the demonstration at different depths to compare how water pressure affects the egg’s shape.  
  * Recreate a similar effect in a microgravity environment (as teachers have done on parabolic flights).  
  * Compare the behavior of an egg cracked in freshwater vs. saltwater.



====Safety Precautions====
  * Only attempt this experiment under proper scuba diving supervision and training.  
  * Do not attempt with raw eggs in public swimming pools (risk of contamination).  
  * Ensure eggs are disposed of properly to avoid environmental impacts.  
  * Avoid sharp shell fragments while cracking the egg.




====Questions to Consider====
  * Why doesn’t the egg white and yolk disperse immediately in the water? (Water pressure at depth keeps the parts of the egg together, like an invisible shell.)  
  * How is this effect similar to jellyfish floating in the ocean? (Both are soft-bodied and maintained by water pressure.)  
  * What would happen if you cracked the egg at the surface instead of underwater? (The egg contents would disperse quickly into the water.)  
  * How does this compare to cracking an egg in microgravity? (In both cases, the egg floats together in a sphere because there is no gravity pulling it apart into a flat shape.)
