The Expired 1970s Patent That Makes DIY Slurpees Possible Without Any Special Equipment

Food scientist Chris Young uncovers a forgotten General Foods Corporation patent from 1970 to crack the code on making Slurpees at home — no frozen carbonated beverage machine required. Using a precise blend of low-methoxyl pectin, guar gum, yucca extract, and extra sugar, he replicates the iconic foamy, slushy texture using just a freezer and a digital scale. The video also covers the surprising science behind why Slurpees need nearly double the sugar of regular soda.
