The key is the tongue.
I know it's hard, it takes lots of practice
The more you have to work with the better.
Use your tongue as much as possible
Move your tongue in circular motions
Try using the tip to move, swirl, and rotate.
It does take time and practice - keep working it
Work with what you have and focus
Once you get the hang of it, it is quite fun
Eventually, your tongue can work and achieve better results
Just remember, it's all in the tongue!
And when you get really good, you can blow a bubble within a bubble - or even a few bubbles within bubbles!
