:-[Haven't tried it yet. I've seen posts about using pvc which I may try. I bought bamboo stalks at a craft store, but when I put them in water they float..... no kidding right.... so right now I have six, six inch pieces submered in water waiting until they don't float any more. It's been about 10 days. still floating. And one of them has started to crack. I went to michaels and found some faux bamboo... Thought that was perfect except they were 4 feet long. I cut a piece to the 6 inches I wanted and it has a metal rod inside it. Not know what kind of metal... I decided not use them.

I was gonna get some, figuring they could be cut to size. do you think the cut edge could be sealed off with silicone, & stuck to rock for a weighted bottom?
