Eggs and density

Floating Eggsperiment!

Two raw eggs from the same dozen - why does one float and the other sink?

Is one boiled? No!
Is one a rotten egg and one fresh? No!

Density expains it!

Both eggs are placed into equal amounts of water in a beaker.
Continue to add salt to one beaker, add lots of salt and dissolve it - the egg in the salty water beaker will float. Why?

An egg is more dense than fresh water and will sink in fresh water.
An egg is less dense than salt water and will float in salt water.

Another everyday example of effect of salt effecting density is that a ship sails higher in salt water than fresh river water!
