Lava rock airstone! (pics)

[tropfish]

So i put a 1in hole in a medium peice of lava rock using a flat headed screw driver, so the tubing was a perfect fit too. I put the tubing in and then hot glues around the hole so no air could escape out. I plugged it in and it's bubbling like mad, it makes my 29g look wicked! and i added the other peice of lava rock on tip of the first and it splits the bubbles so much, its so cool.
Taking pics of bubbles is kinda hard haha but believe me they'res alot coming out.

Heres the pics:
