Please note that all ingredients are in both mL and cups as well as grams and teaspoons. Supply costs can vary depending on your global location and are listed here as Amazon pricing in the U.S.

Calcium lactate powder ($10) (you will need 9 grams or 2.5 tsp in total)
  - you can substitute this with calcium chloride or calcium lactate glutanate

Sodium alginate powder ($10) (you will need 1 gram or  1 tsp in total - which is split in half between two recipes)
   - the 2 oz. packets work great for up to 5 students to use if they are sharing supplies

Water (filtered tastes best, but tap is fine)

Immersion blender OR regular blender

1 medium bowl (should be able to fit 2 cups (500 mL) of liquid)

2 spoons

3 small/medium bowls (should be able to fit 1 cup (250 mL) of liquid in each)

tablespoon and teaspoon measuring spoons

Measuring cups

Syringe  (the size (diameter) of the syringe tip is the size the boba will be)
  - I use a 20 cc syringe (no needle)
  - You could also use a straw, baster, squeeze bottle, or a spoon

A flavoring for the boba
   - no pineapple juice, lemonade, coffee, or orange juice
   - I find that shaved ice syrups, soda, apple juice, mango juice, capri sun all work well (these are not the only flavorings that work though - you can feel free to message me if you have any questions regarding the flavoring you would like to use.)

Baking soda or baking powder may also be needed to adjust more acidic juices.

Optional: Litmus paper (can be found anywhere they sell fish supplies) and is useful to determine the acidity of our flavoring
