I have been looking for new tricks for quite some time. Great idea making a post about it.
I first learned to french inhale the smoke. (out your mouth and in your nose at the same time)
Second I learned how to blow smoke rings.
I can now blow a ring through a ring and another through that ring. (The first ring always disappears though
I recently discovered that if you take the flat of your palm and quickly but gently press it against a lingering ring and pull away again you can make it shrink and grow. It looks kinda cool.
