Thirst Buster is a frosty, non-alcoholic, slushy beverage available at Shell Canada gas stations. It is available in various flavors.
Thirst Busters are made using a mixture of syrup, frozen water, and carbon dioxide. The ingredients are fed into the Slush Buster Machine at different pressures, blended, then pushed under pressure into a stainless steel chilling tank. The tank contains rotating scraper arms to prevent the mixture from freezing. When the customer opens the tap, the machine's internal pressure pushes the mixture out.
