Outside the Box – Juliann Talkington

Science was part of the preschool Spanish class last week. The kids mixed vinegar and water and then added baking soda very slowly. It bubbled. When the bubbles settled they added a little more baking soda. Finally they added some fruit, vegetables and bits of spaghetti. These items sank to the bottom, then rose to the top, then sank to the bottom again. It was an acid-base reaction that produced carbon dioxide. The carbon dioxide attached to the objects and pushed them to the surface, releasing the carbon dioxide to the air, which allow the objects to sink again. What fun!
