I am pretty positive that lots of people have some awareness of the common reactions between two household items. You guessed it! The old vinegar and baking-soda mix! In case anyone was wondering, vinegar and baking soda have an acid-base reaction, where the baking soda (base) and vinegar (acid) combine and release carbon dioxide. There are many ways to have fun with this reaction. You can use it for art with baking soda reaction paintings. You can use it to make bottle rockets. In honor of Halloween, Cougar Club used this activity to create fizzing, oozing – and barfing – pumpkins. This was this multi-step highlight of the day and it came on Halloween! First, we laid down some supplies, which were the pumpkins, carving tools, and gut scoopers. Then kids got into pairs or groups of three (we didn’t have many kids that day) and got to work scooping and designing their pumpkin faces. It was interesting to see which kiddos loved the feeling of the guts and which one disliked the texture. Then, we all began the eruption process. We started with simple reactions, and the kids got to experiment on the amounts of baking soda and vinegar. After each got their first try, they were able to add in different types of bottles for the reactions, adding in different kinds of pops (Mountain Dew, Coke, and Sprite), and introducing food coloring (to make different colors of barf. It was a hilarious thing to see and a great feeling to have the kids so engaged and excited to create fizzing pumpkins.
Have a great restful weekend,
