Vape Tricks

I've been watching some of the videos on Youtube, and the tricks seem pretty cool. It would be fun to learn some of these. The best I can do is blow O's. Can any of you do any of these tricks?

 

I have watched this video before and I just managedto try the third one but not as good as the guy in the video does it, at least I tried hard enough for something similar, thanks for sharing it anyway!

 

I can't do any of these things no matter how hard I try. I'm not sure what I'm doing wrong. The giant rings are just insane.
