When a raw egg is cracked open underwater at depth, the water pressure holds the egg white and yolk together in a jelly-like sphere. It resembles a floating sea creature and demonstrates how pressure and buoyancy act on fluids without a shell.

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

• 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.

• 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.

• 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.)
