Yes, you can make an egg float in water by adding salt to increase the water's density. This creates a higher buoyant force that counters the egg's weight.
The dependent variable in an experiment involving an egg floating in salt water would likely be the level of buoyancy, which can be measured by whether the egg floats or sinks in the solution.
In an egg floatation project, the constant factor used is the density of the liquid in which the egg is placed. By changing the density of the liquid (e.g., by adding salt to water), you can observe how it affects the buoyancy of the egg and whether it sinks or floats.
An egg will float in water if it is old, as air enters the shell over time, increasing buoyancy. A fresh egg will sink in water due to its higher density. If the egg stands on one end at the bottom of the water glass, it is still safe to eat.
An egg can float in water if it is not fresh because as the egg ages, it loses moisture and air enters the shell, increasing its buoyancy. This causes the egg to float due to the air pocket inside it.
Three types of buoyancy are positive buoyancy, negative buoyancy, and neutral buoyancy. Positive buoyancy occurs when an object is lighter than the fluid it displaces, causing it to float. Negative buoyancy happens when an object is heavier than the fluid it displaces, causing it to sink. Neutral buoyancy is when an object has the same density as the fluid it displaces, resulting in it neither sinking nor floating.
No
The density of an egg in water affects its buoyancy because if the egg is denser than water, it will sink. If the egg is less dense than water, it will float. Buoyancy is the upward force that a fluid exerts on an object, and it depends on the density of the object compared to the density of the fluid.
The Buoyancy of an Egg
An egg floating in salt water. The salt makes the water more dense. Since the egg is less dense it floats!
both....and it depends what you are looking to measure if you are looking to measure buoyancy by comparing the two salts then this is the way to do it.

Let's take a walk and talk about this. The force of buoyancy affects everything in the water. It affects a brick. But the force of buoyancy isn't enough to keep the brick afloat. But a brick weighs less under water than it does in air. Take the volume of the brick, take an equal volume of water, weigh the water, subtract the weight of that water from the weight of the brick in air, and you'll end up with the weight of the brick in the water. This is buoyancy in action. The brick weighs less because the water is pushing around it on all sides, but particularly from the bottom. This is true of all objects that sink. Like your egg, for example. It you have a "normal" egg, that is. Do an experiment. Take a bowl of water large enough to hold something like, say, a cantaloupe. Fill it nearly full of water and leave it in the sink. Hold an egg in the palm of your hand, and hold your hand over the bowl. Note the "weight" of the egg. That is, feel how heavy it is in your hand. Now lower your hand into the water. The egg will feel noticeably lighter. That's because the water is acting on the egg to buoy it up, or push it to the surface. That's buoyancy. The egg, however, is just a bit more dense that the same volume of water, so the egg will sink. But the egg weighs very little underwater compared to what it weighs in air. You can feel how light it becomes when you lower your hand into the water. That's buoyancy affecting the egg. For the most part, liquids all try to push whatever is put into them out. Objects less dense than the liquid will float. Those that are more dense will sink, but will weigh less under water because of buoyancy. Buoyancy is the force equal to the weight of the water displaced by an object that is submerged.
you put it in a cup of water or something that has water in it
Oh, what a wonderful project you have there, friend! How about a title like "Salt and the Egg: A Delicate Balance"? Or maybe "Finding the Perfect Salty Solution for Floating Eggs"? Remember, the most important thing is to have fun and enjoy the process of discovery!
