After we put an egg in a glass, when we add salt, the egg goes up from the bottom. Which of the following expressions is correct.

Question

1. The egg is moving up from the bottom.
2. The egg is floating up from the bottom.
3. The egg is going up from the bottom.

[Which one is correct? Can we substitute 'upwards' for 'up'?]

Answer 1

I take it you mean in a glass of water, right?

I think "floating" is probably the most accurate verb here, but all three verbs are correct.

You can use "upwards" rather than "up" if you wish, but it's not necessary.
