Question: Does Adding Glycerin or Corn Syrup Improve a Mixture of Bubble Solution?

Research Report Findings:

My project is about whether adding glycerin or corn syrup will improve a bubble solution. Some bubbles are made of soap and water and some others are soap, water, and corn syrup. The secret to a good bubble is something called surface tension. Surface tension is an invisible bond that holds water molecules together. In plain water, the surface tension is strong and the water might make bubbles, but the bubbles won’t last very long and then there is going to be small bubbles because some other molecules in the water will slightly pull water so the bubbles can float in the air. Soap decreases the pull of surface tension, typically just about a third that of just plain water. The surface tension in plain water is too strong for bubbles to last for any length of time. There’s another problem with just pure water and that is evaporation. It becomes thin and then it’s going to cause the bubble to pop.

There was a boy named David Glaser who did the same Science project as I did and his question was “Do soap and water make long-lasting bubbles?” He did something very cool. He would blow bubbles and he would use the same wand every time and he would measure the tallest bubble with a ruler. He would use different kinds of bubbles made from different ingredients and would blow a bubble and count how long the bubbles would last. And he said if you add glycerin in your soap and water, you will get better bubbles. David Glaser’s longest-lasting bubble survived for 3 months.

I also found out that if you add Corn syrup to a bubble solution it does affect how long a bubble lasts in the air. I found that in another student’s research project. She found that out because she tested that adding ½ cup of Karo corn syrup on average makes the bubble stay in the air for about 48.58 seconds.

My Hypothesis is that the best ingredient to make a long-lasting bubble is Glycerin because I found 1 student and his bubble Lasted for three months and the other student bubble lasted for 48.58 seconds.

Experiment Design:
Step1: First, make your bubble solution, and store them in clearly labeled glass mason
Jars. Use one jar for each different solution and label with the formula using a
Permanent marker. Here are three basics solution to try, but notice that the total
Volume of the solution is kept consistent.

Step2: Now make a pipe cleaner wand for each solution. Pinch a pipe cleaner in the
Middle and give it a kink. Bend one half of the pipe cleaner into a circle and twist
together at the center. Repeat with the other two pipe cleaners, and check that all
three circles are the same diameter.

Step3: Go outside and test your bubble solution. Blow a bubble and catch it on your
wand. Immediately start the stopwatch and time how the bubble lasts. This will take
some practice, so try it out on some extra solution before you start!

Step4: repeat the experiment as many times as possible for each solution.

Step5: Record your data in a data table.

Step6: For each bubble solution, calculate the average time in seconds that the
bubbles lasted. Do this calculate by adding up all of the data for a solution, and
dividing by the number of trials for that solution.

Step7: Make a graph of your data. For each solution, make a bar of the average time
In seconds that the bubble lasted.

Step8: Analyze your data. Which formula worked the best.

Analyze your Data:
I think the best bubble solution is detergent and corn syrup because when I blow it will float in the air a very long time.




Conclusions:
I found out that if you use different ingredients in a bubble solution you will get better bubbles and they might last a very long time. My hypothesis was right.science_fair_140.jpg science_fair_139.jpg


Summary of Project:
First, I went outside and blew my bubbles and I got my wand
and started blowing and I started the stopwatch and I timed
the bubble to see how long the bubble lasted.
