======Bubbling Slime====== **Materials: **{{$demo.materials_description}}\\ **Difficulty: **{{$demo.difficulty_description}}\\ **Safety: **{{$demo.safety_description}}\\ \\ **Categories:** {{$demo.categories}} \\ **Alternative titles:** Vinegar and Baking Soda Slime ====Summary==== {{$demo.summary}} ====Procedure==== - Pour 2 cups of vinegar into a bowl or container. - While stirring vigorously, slowly sprinkle 1¼ teaspoons of xanthan gum across the top to prevent clumping. - Add food coloring if desired and stir well. - Refrigerate the mixture for a few hours to allow the xanthan gum to fully hydrate. - After chilling, whisk the slime until smooth and gooey. If it is too thick, add a small amount of vinegar to thin it. - Spread a layer of baking soda over the bottom of a clean container. - Pour the slime over the baking soda and watch bubbles rise through the slime. - Stir the slime into the baking soda for even more bubbling action. ====Links==== DIY BUBBLY Slime!

(Carbon dioxide, CO₂.) * Why does the slime bubble more when stirred? (Stirring helps the vinegar and baking soda mix more, releasing more gas.) * Is the reaction endothermic or exothermic? (Endothermic—the reaction absorbs heat, making the mixture feel cooler.) * How does xanthan gum affect the reaction? (It thickens the vinegar into slime, trapping and slowing the release of bubbles.)
