I'm going to try this into my plastic primary, got it in the other day and just waiting for a brew day. I'm hoping to have a similar effect when I pour the wort in.

Not to burst your bubble before you use it, but be prepared for it to clog. I have one and have tried to use it twice over the years. Both times it clogs pretty quick with hot break/cold break and hop debris.
Just thought I would mention it so you keep an eye on it.
