Combining flavor, fun, and chemistry, the spherification kit is a great and tasty introduction to food science! The kit contains food-grade versions of three chemicals used in molecular gastronomy recipes to turn liquids and semi-solids (like juice and yogurt) into tasty spheres that pop in your mouth. We've included a syringe to simplify the making of uniform small balls, but you can make larger food spheres using a tablespoon from your kitchen.

By following the simple instructions in our food science spherification projects, students can enjoy hours of chemistry exploration for fun at home or for a science fair project. The kit has enough materials to do several of the projects or multiple repeats of a favorite project—and all the results are edible!

As a bonus, this same kit can be used to do an unusual human biology project. Using the chemicals in the kit and some colored water, students can model how blood clotting works and experiment to see what factors disrupt normal blood clotting.

Instructions for this kit are available online. See below links to the instructions and more.

You will also need from home:

Depending on which project you are doing, a blender, graph paper, water, food scale, food items, and common kitchen utensils may be needed. Please consult the instructions for each project for a complete list of additional materials.


Instructions are NOT included with the kit, but are available online from Science Buddies.



Each Spherification Kit contains:

  • 50 grams Sodium alginate, food grade
  • 50 grams Calcium chloride, food grade
  • 50 grams Sodium citrate, food grade
  • 1 60 cc Plastic syringe
