Bubble-ology

Question: Which bubble solution will produce a bubble that lasts the longest?


Hypothesis
We think that if a bubble solution contains glycerin, then it will produce the longest lasting bubbles.

Materials and Equipment
  • 3 medium mason jars labeled Solution A:Distilled Water;  Solution B:Glycerin and Solution C:Corn Syrup
  • 3 cups + 1 Tbsp of Distilled water
  • 90 ml of dish washing liquid detergent
  • 15 ml of glycerin
  • 15 ml of corn syrup
  • 3 bubble wands
  • 3 chop sticks to stir solution
  • 6 graduated cylinders to measure liquid ingredients precisely
  • A stopwatch
  • Label maker to record results and put into observation chart



Procedure:
We have labeled 3 mason jars A, B, and C.  Each have different solutions.  Solution A has the control of the experiment, 1 cup of distilled water and 2 tablespoons (or 30 ml) of dawn dishwashing detergent.  In order to keep the volume consistent with solutions solution B and solution C, 1 tablespoon (or 15 ml) has been added to solution A.  Solution B has the control in addition to 1 tablespoon of glycerin (independent variable).  Solution C has the control in addition to 1 tablespoon of corn syrup (independent variable).

We will blow bubbles and get 3 samples from each solution.  We will time (with a stopwatch) and record how long the bubbles from each solution last before popping.  Finally, we will add the average of the data collected from our trials.  Then we can determine which solution made the longest lasting bubble.

The Science behind it

Glycerin forms weak bonds with the water molecules and slows down the evaporation process, thus improving the life span and durability of the bubble.
Conclusion:
Our hypothesis was that a bubble solution containing glycerin will produce the longest lasting bubbles.  Our results support our hypothesis.
