Small top, big container, used for pouring rather than retrieving product.<BR/><BR/>Curiosity and observation. Good combination.Heidicraftshttps://www.blogger.com/profile/16490630214131313709noreply@blogger.comtag:blogger.com,1999:blog-10220498.post-21343901539679396082007-07-18T06:19:00.000-05:002007-07-18T06:19:00.000-05:00I'm posting an addendum.

If it is only narrowing for the lid, then it doesn't count.<BR/><BR/>Maybe we should conduct an unbiased experiment. We could post a series of glass containers and let everyone vote. Maybe we will be able to find a pattern.Mr. Lucchesehttps://www.blogger.com/profile/11489214765844797652noreply@blogger.comtag:blogger.com,1999:blog-10220498.post-38243713526741136682007-07-17T22:03:00.000-05:002007-07-17T22:03:00.000-05:00Heidi: hmmmm, and I wonder if the shape of the con...Heidi: hmmmm, and I wonder if the shape of the container top you're pouring the milk from changes the fluid shape. I'll have to start playing with my food and observing. Thanks for a future conversation topic.<BR/><BR/>Tony: so even if, say, the container is a total of 2 inches tall, with the bottom 1.5"s being of a round shape, say 3" diameter, and the top 0.5" curves in a wee bit (but is still wide), that would be a bottle in your world.<BR/><BR/>Maybe this is one of those fruit/vegetable types of discussions and there are containers that could be in both camps.<BR/><BR/>Ms. CookieAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-10220498.post-13458135999596629402007-07-17T20:10:00.000-05:002007-07-17T20:10:00.000-05:00I say if the container has a neck, and by that I m...I say if the container has a neck, and by that I mean it narrows at the top with at least some section of negative curvature, then it is a bottle. If it doesn't narrow at the top, or if the curvature is positive, then it is a jar.Mr. Lucchesehttps://www.blogger.com/profile/11489214765844797652noreply@blogger.comtag:blogger.com,1999:blog-10220498.post-39116949888787485032007-07-17T13:19:00.000-05:002007-07-17T13:19:00.000-05:00A cool math-y conversation.What has always fascina...A cool math-y conversation.<BR/><BR/>What has always fascinated me, but I don't even know know how to start investigating it, is the shape formed by a fluid in the state of being poured.<BR/><BR/>If I wanted to make a sculpture of milk being poured from a jug to a cup, what shape is the milk? It is smooth, but has little folds that seem to be at regular intervals.Heidicraftshttps://www.blogger.com/profile/16490630214131313709noreply@blogger.com
