Singing through a straw

I've seen some articles and watched videos (Ingo Titze) on singing through a straw but still kind of not sure what the benefits are. So i guess my question is what are the benefits of it and are there any straw routines/exercises you guys can recommend? Thank youuuu :)

Hi, Japhet! Here's a new lesson explaining how to use the straw with some exercises: https://www.youtube.com/watch?v=EecSsVgM3TM.

And here's an article explaining the benefits in detail: https://www.voicescienceworks.org/straw-phonation.html. 

You can sing any exercise through a straw (except for belting exercises), but this channel has a ton of straw warmups for you to check out: https://www.youtube.com/c/SingingStraw/videos.
