Today, my class did a science experiment on explosions, and we collaborated with another fifth-grade class. Our unit in Mystery Science was about acids, so that explains the explosions.
This experiment was SUPER cool, and my group was very excited to do it. We used purple cabbage water, water, vinegar, baking soda, and baking powder. We experimented with these items to see which ones would react or explode.
We were told to place some cabbage water, baking powder, and baking soda on a plastic sleeve and then drop vinegar onto the materials. We also had to make two piles of each item and add water to one of them. This way, we could tell whether the reaction happened because of acid or simply because a liquid was added.
When we did the experiment, we discovered that baking powder and baking soda were the most reactive. They fizzed and foamed when vinegar was added. The cabbage water did nothing, which surprised us!
After the experiment was done, my team was a little bored, so to liven things up, I poured the remaining powders into the vinegar cup and quickly closed the lid. It had already started foaming before I even put the lid on, but it was still very exciting to watch.
Because it was one of my friend’s birthdays that day, my teacher did something SPECTACULAR to celebrate. I swear, it was a SPECTACLE! After the other class left, my teacher dropped a tablet into a cup and poured vinegar over it to try to make it explode. She tried it with two tablets, then three tablets, then inside a hand-soap bottle, and even inside a balloon!
She also said she would do another explosion experiment tomorrow, so I am really looking forward to it.
