How do you whistle using your fingers?

[Pootle]

Always wanted to learn

[Skids]

I wish I knew, I'd love to be able to do it. Even when people show me I still can't.

[dove]

use ur second and 4th finger together, then roll ur tongue back and place fingers on the top of ur folled tongue and blow.  practice makes perfect!

I have been able to whistle with my fingers since I was 12! Not very ladylike, but it has come in very handy over the years! I whistle the loudest & more piercing with my two little fingers & as dove has described.

I have been shown how to hundreds of times by loads of different people and I still can't do it; I have never even come close.

Another one I have never been able to do is the drum roll using your tongue and teeth.

Dove is closest for me.

I remember teaching myself when i was 13ish too.

You can use any fingers including thumbs and fingers from only one hand.

Fold you tongue back and use the fingers to press it down and dont BLOW, as dove suggested,whistle as normal.

give it an hours practice and you'll have it
