Micro Bubbler

Hey GrassCity, this isn't my first post but I do believe it's my first thread I was very productive one day and made myself a very micro bubble, out of a tall pill bottle. lol.
 
I used the pill bottle (is watertight), a short metal stem with a pen section in it. If this isn't safe please tell me, I feel like it's quite far enough from the flame. A straw, and a metal bowl. Made it in like 15 or 20 minutes, and it turned out to be airtight and doesn't slash water anywhere. Tell me what you guys think for such a fast rig? PS that pen piece isn't a cap, it's a thick section of the pen that I cut to size.
 

 
 
 
I've used it, it worked nicely and was impressively smooth. I have plenty of pieces but sometimes it's just fun to make your own

 

Thanks guys. I have plenty of good glass and GonG pieces, buuuuut sometimes the McGuyver in me is too strong haha. Though it is ghetto I am really impressed with how it hits. I also dig the Bacardi bottle big time
