Editing Snow cone (section)

===Theaters===
By the 1870s, the snow cone's popularity had risen to the degree that in the warm summer months, theaters would sell snow cones to keep their patrons cool. Because of this association with the theater, snow cones were thought of as an upper-class commodity. Signs in theaters instructing patrons to finish their snow cones before coming in to the second act are the earliest tangible evidence of snow cones. In the Baltimore theaters at the time, hand shavers were used to shave the ice. In the 1890s, many people started to invent easier ways to make snow cones. In that decade, patents for electric ice shavers were filed.<ref>{{cite web|last=Zay|first=Libby|publisher=[[about.com]]|title=Summer in Baltimore: Snowballs Are the Essential Sweet Treat in Charm City|url=http://baltimore.about.com/od/fooddrink/a/Summer-In-Baltimore-Snowballs-Are-The-Essential-Sweet-Treat-In-Charm-City.htm|access-date=25 November 2015|archive-url=https://web.archive.org/web/20170313202253/http://baltimore.about.com/od/fooddrink/a/Summer-In-Baltimore-Snowballs-Are-The-Essential-Sweet-Treat-In-Charm-City.htm|archive-date=2017-03-13}}</ref><ref>{{cite web|last=Mayhugh|first=Jess|publisher=[[Serious Eats]]|title=The Snowball: A Baltimore Summer Classic|url=http://www.seriouseats.com/2014/08/snowball-baltimore-shaved-ice-best-snowball-shacks-maryland.html|access-date=25 November 2015|archive-date=25 November 2015|archive-url=https://web.archive.org/web/20151125230931/http://www.seriouseats.com/2014/08/snowball-baltimore-shaved-ice-best-snowball-shacks-maryland.html|url-status=live}}</ref>
