This kind of vinegar bottle has the straightest neck I've found. The close up doesn't look straight due to the angle of the camera. This is my favorite slide of all I've tried.

How I make my vinegar bottle slides. I clamp 2 pieces of 2x4 to a table at a right angle and another chunk of wood to support the neck. I put the bottom of the bottle in the right angle and turn it with my left hand while holding a glass cutter against the neck with my right hand. I make one score around the neck. I use a piece of blue painter tape around the neck as a guide to keep my score straight. Then I pour boiling water over just the score while turning the bottle and then stick it into a can of water and ice. I repeat this 2 or 3 times until the end falls off the neck. Then I measure for the length of the slide and repeat the whole procedure. To finish it I use little (4" x 4") squares of wet-dry sand paper on a small flat piece of wood (to protect the coffee table) and grind the end of the slide on that. Keep it very wet by dipping often in a bowl of water. I start with 60 to 150 grit, whatever I have on hand, to take out all the imperfections and 220 to slightly round the edges inside and out. I then move to 400 grit and then 600 to finish it. The sanding takes 1 to 3 hours depending on how good the break was. I usually do this while watching TV or chatting with a friend as the sanding is a fairly mindless and boring task.

And you know, many of us don't think it's odd at all to buy a product based on the 'slidability' of the bottle's neck! Looks amazing!
Got a bottle of this in the cupboard. Bought it for the same reason.
Super nice.
