Acid in your tummy. .

When you have a tummy ache you take medicine to make yourself feel better. We tested two pills and baking soda mixed with  vinegar which acts like the acid in your stomach. We used strips to measure the level of ph it contains. We did tums and the generic pills to investigate what one worked better. Since its generic I knew it would have worked super good but the baking soda bubbled like crazy. I guessed it right and the tum's ph was the smallest however the baking soda was the biggest.
