The nine Da Vinci Science Center partner companies, including defending champion PPL Corp., are expected to participate in "Ice Cream Wars 6.0," 11 a.m. - 2 p.m. Jan. 11 at the center.

Those attending may taste the ice cream concoctions, the recipes for which will be activated with liquid nitrogen, and vote for their favorites. The corporate team that collects the most votes wins the annual Ice Cream Wars Championship, including a trophy to keep for one year.

Teams decorate their stations, distribute gifts, dress colorfully, and cheer enthusiastically throughout the competition. Judges' Awards are given for spirit, creativity and other attributes.

"Ice Cream Wars" is said to be "a sweet chemistry lesson." The liquid nitrogen, which stands at negative 320 degrees Fahrenheit, chills the ice cream ingredient mixes immediately while it warms and evaporates rapidly. The resulting creamy treats are safe to eat in approximately five minutes.

Teams, in addition to that of PPL, include those from 401! Creative, a division of Weidenhammer Services Corp.; ATAS International, Inc.; Avantor Performance Materials; B. Braun; Just Born; LSI Corp.; The Morning Call Media Group, and WFMZ 69 News.
