What's "胡胡" 聲?
更新3:
I've tried , and I think the sound produced is "胡胡" 聲. But do U think it's still safe to be used? Will I break it if I add boiling water? cuz I guess it should be at least 15 years old.

It doesn't matter that I can't use it. Just want to know if I can really use it safely or not. So it should be OK to fill in with cold water, right?
