I found a Turkey Baster at Albertson's for $2.50, and used that instead. I boiled some filtered water in a pot and sucked the water up through the used cartomizer, until the water coming up into the baster was clear again. Blow all the water out... OR... you can make a simple centrifuge.
Hmm.. I think I'll make a post on that centrifuge process and maybe even a video. For now I'll make a post. I'd wanna refine it more before I make the video.
Edit: I had to cut some of the tip off and shave down the inside of the tip a bit for it to fit properly. I'm on the lookout for some rubber-like tubing that will fit the carts perfectly.
Edit #2: Haha... Already been done! Of course, right? Nothing new under the sun. Look at me, thinking I'm all creative... SMH
The taryn spin method seems a bit more complex than mine, but also seems to be more reusable than mine. Oh well.
