I’m getting more and more familiar with this glassy, et, I mean classy and innovative small hand water pipe. And with that familiarity, smoother hits than otherwise possible without water filtration. So while it’s requiring a learning curve for me at least, it’s absolutely worth it to have a portable solution that doesn’t require me to inhale fire! I am finding that filling just enough water to cover the down-stem inhale holes and either a tiny screen in the bowl, or a light press of the ground flower works well. Love Grav products very much (particularly the inline bubbler)!
