Normaly if an egg floats it is bad and should be discarded. As the egg ages air pockets enter the egg, that's why they float.

A change in buoyancy. If the egg is more dense then the water (or whatever liquid it is in), it will sink.

Objects that are more dense than water will sink, while those that are less dense will float. Eggs are more dense than water, so they sink. Water, on the other hand, is less dense than the egg, so it floats. This is due to the principle of buoyancy.

It all depends on the density of the water and the egg. The egg is denser than water. Therefore, it will sink. But if you add salt or anything and dilute it in the water the egg will float because the water becomes denser then.

Why does an egg flout or sink in water?

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.


How do you make an egg sink?

Which object will sink in simple water and float in salty water?

A Rock would obviously sink in water and a egg would float in salt water Believe it or not bowling balls that are denser than water float!

Why does an egg sink in water but float in salt water?

Salt water is denser than pure water.


Will an egg float in salt or fresh water?

What happens when you put an egg in tap water?

When you put an egg in tap water, it will sink to the bottom if it is fresh. Fresh eggs have denser contents, causing them to sink. If it floats, it is an indication that the egg is not as fresh and has probably started to spoil.


What happens if an egg is immersed in salt water?

If the egg is good and not spoiled it will sink down. If the egg is spoiled it will float up.


Will a hard boild egg sink in vinger or water?

A hard boiled egg will sink in water because it is denser than water. However, it will float in vinegar due to the lower density of vinegar compared to the egg.


Will an egg float better in salt water than regular water?

Salt water. Salt water is very hypotonic and will force the egg to float. Regular water is hypertonic and force water in. Causing the egg to sink like the Titanic.
