My Equipments

As i researched my experiment in how to make bubbles, i found out that u need to put glycerin in too. I didn't know what it is so i researched it and found out that it is a liquid substance that is used to mix with other liquids to make i sweet. Although i did not have this item so i decided to use sugar. I researched more and found out that you can either use sugar if u don't have glycerin.

I have recorded my results

I had no idea my experiment was going to be hard. I thought about how i was going to measure the bubble,  but it was impossible. So i decided to do my teacher's idea, to record from when it is blown to when i forms the bubble by a stop watch. This was WAY easier than trying to measure by a ruler! In the end i took pictures recorded my results and turns out, the dish washer was the best liquid substance to use for bubble solution.
