My mini craft project to day was crafting a bottleneck slide from a recycled wine bottle, to use on my cigar box guitar. I needed a stubby one to fit my hands and thinner neck width on the 3-string guitar.
My husband sent me this Make video link on how to cut glass bottles last night, and this method works beautifully!
I picked up a glass cutter today, a friend donated a bottle, and I got the kettle boiling. I laid a dishtowel in the bottom of the kitchen sink, just in case of breakage. I got a relatively clean cut, which I smoothed out with fine wet/dry sandpaper (used it wet). Beauty!
So if you want to make a slide, or just pretty tumblers or a vase, I highly recommend Dan Rojas’ method. Also, I dig the part of the video when his cat saunters into the view of the camera and he starts talking to it.
