The student said: "You just need to put a little more salt in the water, and then do it step by step, first of all, take out a cup bigger than the egg, but not too big a cup, otherwise you have to put a lot of salt." Then I put the eggs in and added a few spoons of salt. But the egg didn't listen to me and wouldn't float. What can I do now?
I thought, "Why do eggs float in the sea? It's because the sea is buoyant, and that's why the eggs float. But I've already put in a lot of salt.
Suddenly, my mom came over and said, "Son, what's bothering you?" I said: "Mom, I put the salt in the water, and then put the egg in. But why doesn't the egg float?"
Mom said, "Maybe the salt hasn't melted yet." I took the eggs out and stirred them with chopsticks, and the salt melted. I put the egg in, and it floated up, I was so happy, the egg finally floated up!
