Making Sherbet

Today we made sherbet. I mixed a part of baking soda, citric acid, raro and icing sugar all together. My hypothesis was that it wouldn’t react to my tongue and that it would just taste sweet. It felt like a big bang when the sherbet touched my tongue. I could feel it fizz and foam all around my mouth. The citrus taste was from the raro and citric acid and the sweetness was from the icing sugar. I think the foaming reaction came from the baking soda.
