How can i apply the theory that egg floats with the right amount of salt to life?

i have done this experiment. it was to see what amount of salt would make an egg float and it came out 3 tablespoons of salt. and i had a question to asnwer. it was ';how can you apply this experiment to life?'; so do you of you know how i can apply this to everyday life...i already have one and it is floating high-dense boats for children fun....any others....please help meHow can i apply the theory that egg floats with the right amount of salt to life?
Well I was going to say using it to help with the design of Naval Ships. How they build them so big and massive, yet keep them afloat. You could also use the idea of Icebergs and how the amount of salt underneath an Iceberg is more than four times the concentration of salt in the water around it.How can i apply the theory that egg floats with the right amount of salt to life?
You might try an airplane and the lift factor: an airplane can't ';fly'; unless the right amount of force (lift) is present. Also maybe a submarine and the way it sinks and floats, or a person when they fill their lugs with air so that they can float on the water, or a SCUBA diver and the tanks they use for oxygen and being raised to the top, or even water and oil. Water floats on oil because it is less dense. This means that with the molecules being arranged in a specific way and the repulsion between the molecules that it allows it to float. Take your pick.
