Explore the fascinating world of molecular gastronomy with No More Empty Pots, who will be demonstrating the food science process known as spherification—a method that turns flavored liquids into popping pearls using simple ingredients and chemistry. This hands-on activity introduces students to real-world science concepts such as chemical reactions, states of matter, and food-safe lab techniques.
Participants will:
Learn how sodium alginate and calcium chloride interact to form edible spheres
Use measuring tools and droppers to create their own pearls
Observe the reaction in real time and experiment with timing and texture
This experience connects food, chemistry, and curiosity, encouraging students to see science as something they can touch, taste, and explore.
More about Spherification
Spherification works through a chemical reaction between sodium alginate, a natural thickener extracted from seaweed, and calcium chloride, a type of salt. When droplets of the alginate mixture are dropped into the calcium solution, calcium ions cause the alginate molecules to link together, forming a thin gel “skin” around the liquid. This reaction creates a squishy, poppable sphere—just like the ones found in boba tea or fancy restaurant dishes.
Who: All-ages, but designed primarily for individuals/families with children age 6 & up.
