Was at "Denny's" a week back & had an Interesting Syrup bottle! Pretty darn neat, as it Doesn't drip, & pouring is very controlled. I did wonder about it not having a lid, but it must pass the health inspection. Can't explain the dynamics of it like Shawn could, but just know it has a tiny tube going inside the bottle, from an air hole. That controls the flow, & as soon as you turn the bottle upright, nothing drips or runs down the outside. Neat!
