"There are many bottles on the market that have been designed specifically 1) with larger caps, as they allow the bottle to be sat cap-down (e.g. ketchup); 2) with a large draft along the sides of the bottle for thicker formula (many mass-premium lotions are very thick); and 3) without small form details like crevices where the formula can get stuck. All of these features help move and 'prep' the formula to be at the bottom, ready for dispensing, whenever the user needs it. I have done structural designs where this seriously encroached on interior volume and limited creative freedom. And when bottle width/depth/heights are limited at shelf, we almost always had to cut back on volume (without, unfortunately, reducing the price accordingly). Add to that the amount left in the bottle (e.g. leftover 1oz in a 5oz bottle is more significant than 1oz in a 6oz bottle, spread over millions of bottles), consumers often receive much less than what they paid for.For a product like glue, needing a wide-mouth cap for quick dispensing works against the thin nozzles that many users need for precise application. Even newer fruit preserves (with additives to make the preserve more "slidable") have been put into squeeze bottles (again, caps at bottom) to alleviate the hassle of spooning (with a knife, no less) from the bottom of the jar. If I can easily pour the preserve to the edge of the jar, then I don't see a need for a squeeze bottle with a large cap. (Jars tend to have better stackability on shelf than squeeze bottles, so there's some added bonus there as well). Of course, this is presuming LiquiGlide is or eventually becomes food-grade safe.In any case, as with all new technologies, the upfront costs will need to be defrayed over time with volume and market penetration. Even modern tubes and bottles are actually laminates with 3 or more layers—to block UV, preserve formula, provide particular surface finish, etc.—that I don't see LiquiGlide being cost prohibitive for too long. In short, I can see this being a huge plus for the industry and the designers who do this for a living, and I'm glad Elmer's is spearheading this."

"It's perfect for a classroom setting—such as a high school art class—where workspace might be limited but many people/students need to be doing the same thing at the same time. It wouldn't make sense to have numerous paper cutters that take up space, nor would it time efficient to use a paper cutter, then switch to an X-acto/scissor for the curves, and then switch back to a paper cutter for the straights. Plus, there's inherent concern (valid or not) in giving a bunch of kids X-actos and paper cutters when you can have multifunctional scissors. In arts & crafts projects (such as the large letter in the video), a mix of different shapes are typical. And some people may want to cut straighter, but using regular scissors give them a zig-zag edge; leverage a table edge can make trying to cut straight more satisfying."
