Economical - 🥼✨ Dancing Rice Experiment A fizzy, bubbly science project where rice comes to life—fun, fast, and fascinating! 🧪 What You’ll Need: 1 clear container (glass or plastic) 1 cup water 1 teaspoon baking soda 1 tablespoon vinegar A handful of uncooked white rice Spoon (for stirring) Food coloring (optional, for extra flair) 🧭 Step-by-Step Instructions: 1. Prepare the Base Pour 1 cup of water into your container. Add a few drops of food coloring if you’d like some extra visual excitement, and stir. 2. Mix in the Baking Soda Add 1 teaspoon of baking soda to the water and stir until fully dissolved. This is your chemical reaction base. 3. Add the Rice Drop a small handful of uncooked white rice into the container. The grains will sink at first—don’t worry, the show’s about to start! 4. Trigger the Reaction Pour in 1 tablespoon of vinegar and watch the magic! Bubbles of carbon dioxide will form, lifting the rice up like it's dancing. 5. Watch the Dance The rice will float up as bubbles stick to the grains, then sink again as the bubbles pop—creating a mesmerizing, dance-like effect! 6. Keep the Party Going To extend the fun, continue adding small amounts of baking soda and vinegar alternately to restart the bubbling reaction. 🔍 Science Behind It: The reaction between baking soda (a base) and vinegar (an acid) creates carbon dioxide gas. As these bubbles cling to the rice, they lift it up. When the bubbles burst, the rice falls—this up-and-down motion is what creates the “dance”
