Hannah was Super Scientist for Mrs. C’s class! She showed us how to make an exploding sandwich bag! Wow! First, she put 1/4 cup of warm water into the sandwich bag. Then, she added 1/2 cup of vinegar. Next, she put 3 heaping teaspoons of baking soda into a tissue. She folded the tissue up to keep the soda inside. She then quickly dropped the tissue into the bag and sealed it. The bag expanded until we heard a loud POP! It was awesome. The baking soda and vinegar mix to create an acid-base reaction. The two chemicals create a gas and fill the bag. When the bag can’t hold anymore gas…POP!
Way to go, Super Scientist Hannah!!!
