Bubble Lab: 02/4/21

For this lab my partner and I had the goal to record and observe the the color, physical structure, and timing of bubbles. To start we first labeled 4 transparent cups A-D. each cup was filled with 1/4 cup of water, then we later added specific measurements of detergent, sugar, and glycerin. Below is a picture of the table we used, and our observations of each bubble.

CUP A: the contents of this cup was water alone. When we tried to create a bubble with only this liquid we found that it was not possible. 

CUP B: the contents of this cup consisted of water and one teaspoon of laundry detergent. We discovered that this solution was much easier to work with, and we were able to get strong long lasting bubbles. They seemed to last 40 seconds or more with out manipulation, and up to 1 minute when paired with other bubbles that formed a wall. The colors we noticed were blue, red, and green, and noticed the bubbles began to ripple before the popped. The photo below is the bubble with only water and detergent.

CUP C: the contents of this cup consisted of water, 1 teaspoon of detergent, and 1/4 cup of sugar. This bubble was easy to create and lasted up to 63 seconds. We noticed that when paired with other bubbles it was difficult to get them to last. The colors we recorded were blue, green, and pink. Also we observed that the bubble took an oval shape before it popped as seen in the picture below. 

 

CUP D: the contents of this cup consisted of water, 1 teaspoon of detergent, and 10 drops of glycerin. We noticed these bubbles were very malleable. They were almost elastic and held their shape for long periods of time, up to 2 minutes before popping. The bubble did not seem to last as long when in contact with another, they seemed to only last a few seconds. The colors we noticed were blue, green, and red as seen in the picture below. This bubble also seemed to take an oval shape before it popped.

Throughout the lab we determined that with the addition of sugar and glycerin, bubbles lasted longer and were easier to blow. I had a fun time learning about how and why the colors appeared through light waves, along with what solution made them last longer.
