What can I say to express the greatness of water flowing from the faucet?

You can say all of these words, but not in all contexts. You'll have to be more specific and provide clear examples before I can give you a qualified answer.

i think you cant say big water and small water.but u can say

big stream, small stream;

rapid stream, slow stream; or

wide stream, narrow stream

Hi,

Here are examples from a conversation between a dad and a toddler:

A: Let's wash hands. Reach out your hands.

B: The water is too big (?). Can you turn down the faucet ? (I am not sure whether turn down/up the faucet is correct).

A: Now the water is small (?).

B: Good. Thank you.

Can you check out these conve

Stephen - I presume you want the toddler to hear and learn proper English, right?

It's important to be as clear as possible.

Here is an example of how a conversation between a dad and a toddler should go:

A: Let's wash

Thank you very much, JohnParis.
