First, it must define how salty it is, a salty water could have density between 1 g/cm3 to 1.2 g/cm3 at saturated concentration. The chicken egg is 1.04 g/cm3 with some little variation and would sink when the salt concentration reach about 6 - 7%.
Egg of different species would have different density but I had no data if there is any egg species that may float in saturated salt concentration or not. Far as I knew, the egg shell for chicken is around 2 g/cm3 and it would mean any animal with more shell thickness per volume would had higher density.
There are tents designed to Float in water. But not all tents designed to float.
Virtually all types of rock will sink in water. The only rock that can float on water is pumice.
plastic will float in water because it is lighter than oil
== Yes because the volume of water displaced by a cherry is enough that the buoyant force of the water is able to counteract the force of the cherry's weight.==
You can boil the water until all the water evaporates and then you're left with just the salt
add vinigar to the water
you can add salt to water to make the egg float because of it's density
it is because salty water is made of the dirty water which come from mountains melted water its small salty particles makes all the water salty thats what the reason is about salty water
rocks metal eggs dirt or sand all sink some woods sponge plastic aluminum cans all float
..purify the water to separate the mudd salty water..that would be all,,thank you=
All vegetables float in water
If the eggs in the nest are more than a week old, I just put them in water to see if they float in water. If they float, they're no good. If they start to turn upward like they want to float, you're taking chances. If they're dead still and don't float at all, then they're fresh.
All the oceans and seas of the world are a huge source of salty water.

It depends upon the type of the plant. All the plants do not survive in salty water, few of the species of plants do. They are called Halophiles that grow in salty water they are not harmed by the salty water.
To test an egg for freshness, place it in a container of cold water. Some eggs that are not fresh but are still good will raise up a little on one end or even stand up on one end. The eggs that are bad will float all the way off the bottom of the container, will not touch the bottom and should not be used.
There will be a bit of variation between eggs, but an investigator might do something like this: Get a container like a soup pot. Put a known volume of water in it and have it about 4 or 5 inches deep. (Measure!) Record your data. Borrow a half dozen eggs from the fridge. Get permission to do this. The "selling point" is that the eggs will be returned in tact and in the same condition when you're done. Get some salt and a tablespoon to measure that salt. Gently add the eggs to the water, then add a tablespoon of salt. Stir gently to get all the salt to dissolve. Patience is required here. If you want to "speed up" things, you might consider getting a cup and dipping it into the solution, lifting it out, and pouring it back in. This might be a better way to agitate and mix the solution. It's "safer" as well. You want all the salt to dissolve, and you don't want to break the eggs. It's important that you get all the salt to dissolve before adding more, and (at the risk of repeating it) patience is a must. Though hot water would help, you're not using it because you want the eggs to be like they were before you borrowed them. Make sense? Keep adding a tablespoon of salt, stirring (or "mixing" by "cupping" out water and pouring it back in), and then waiting to insure it's all dissolved. Keep recording what you do and also the results of your actions (your observations). Eventually the eggs will float. See how much salt you had to add to the water and take the amount of salt and water and make a calculation to determine salinity. If you care to, repeat the experiment. You'll have discovered how salty water has to be to float eggs. Lastly, you'll write this up and turn it in.
