Why I choose this topic

I decided to do my project on square bubbles. I mean who doesn't love bubbles! I first researched this topic to see if it was possible, and surprisingly it was! I found out several people have done it before. So, I decided to not only make a square bubble, but to add and substitute different ingredients to make the bubble last longer. I did this by using two simple substitute ingredients; glycerin and corn syrup. My hypothesis was that the glycerin was going to make the bubble last longer than the corn syrup. And when I tested this hypothesis, I was correct!
