Step One: Combine 1 cup flour, 2 cups baking soda, 1 cup water, and a few drops of food coloring in a saucepan.
Step Two: Cook over medium heat. Stir until it looks like mashed potatoes.
Step Three: Remove from heat and place in a glass bowl.
Step Four: Cover with a cloth until cool.
Step Five: To make the dough into fizzy dough add vinegar for a bubbly reaction that is fun to watch and play with.
Step Six: Put the fizzy dough into a bin and pour and paint vinegar all over the dough. It became a squishy sensory mess of a dough, but still squishy.
Step Seven: Add more vinegar for a thinner substance.
Step Eight: Add a pre-handwriting and cursive letter formation aspect to the sensory dough. Have the child roll out snakes and make lower case letters. Fizz them for the sensory fun of it.
Step Nine: Dip a paintbrush in a cup of vinegar and "paint" the letters for letter formation practice. Encourage the child to paint the letters in the correct way to practice letter formation and handwriting.
Step Nine: Next, use the fizzy dough as a starting point to learn the beginning lines and curves of cursive handsriting. Learning the letters can be easy for children, but the connecting lines can be confusing who are used to printing words. Form a long "snake" with the fizzy dough by rolling it on a table surface. Make the "snake" of dough to be long enough to form several cursive letters in a row. Use the dough to form beginning cursive strokes: a series of lower case letter "i", letter "t", letter "m", letter "l", letter "c", and letter "u". Connect the letters as pictured.
Step Ten: Add vinegar for a fizzy and sensory reaction. Paint the letters with a paintbrush.
