This makes a small batch. For more solid bubble bars, double the recipe. You will need: 1/2 cup Baking Soda 1/2 cup Corn Starch Optional: 2 tbs. Cream of Tartar 2 oz. of liquid Bubble Bath (any brand will do) Optional: Color - Food color or an old eye shadow (crushed up fine) Cookie Cutters Wax Paper lined Cookie Sheet (dust wax paper with corn starch) In a large bowl, mix baking soda, cream of tartar and corn starch together with a wire wisk. Slowly add liquid bubble bath (and optional colorant) while constantly stirring dry ingredients with a wire wisk. Now get your hands in there and knead the mixture until it takes on the consistency of dough (may take awhile - keep kneading). The mixture will be sticky at first but will begin to take on the correct dough like consistency the more it is mixed with your hands. Once dough like consistency is achieved, take the dough ball and place on corn starch dusted wax paper. Pat down the dough ball about 1/2 inch thickness and use the cookie cutters to cut out shapes and make your bubble bars. Use you hands to form left over dough into shapes or roll in balls. Let the bubble bars dry for 24 hours before use. After dried and hard, place bubble bars in a zip lock bag for storage. To use, crumble 1/2 to 1 full bubble bar (depending on size) under the force of running bath water and ENJOY YOUR BUBBLES! NOTE: I have revised this some so it can be made by people that do not have Cream of Tartar. If you have it, use it. If you can buy it cheap great but it's kinda expensive at the grocery store.
