Why do eggs float?

When I was in the Chinese class, Teacher Wang gave us a scientific experiment. Is the name really called egg floating in salt water? I think it is unlikely. So Teacher Wang found a cup that could be put into the egg, filled with water, put the prepared eggs in, and saw the eggs slowly sinking. At this time, the teacher told us: "This is because the egg is heavier than the water, so it will sink." We seem to understand and understand. Then the teacher took a bag of salt and poured it into the cup. The egg slowly rose a little. The teacher then went to some more. Wow! I saw a miracle! The eggs are floating up! Drifted to the water! The students suddenly applauded... The teacher told us that this is because the salt is bigger than the egg, so the egg comes up.

Through this experiment, we understand why eggs can float. The scientific experiment around me is really fun!
