Why do my glass wine glasses sound like plastic when full?!?!?

Transcript

Someone could explain this to me because maybe I'm just not understanding. But I have two wine glasses, right? They're glass. They sound like that when they are empty. Okay? Now, if I put water in them, they sound like this. They sound like plastic now. I'm really confused. I had a bunch of people over for dinner last week and we went to go cheers and it sounded like plastic cups and they were like, oh, I didn't realize these were plastic. And I was like, they're not. They're glass. Why does that happen? I'm genuinely so confused how this happens.
