Does adding salt or sugar to soap solution have any impact on how well bubbles form?
Lab Question: Will salt or sugar change the ability of a solution to make bubbles? Lots of “bubbleologist’s”pursue the perfect bubble always trying to enhance the standard bubble blowing solution and the question is well anything really work? Hopefully this experiment will give us information that could answer whether this solution is positively or adversely affected by these compounds.
Hypothesis:
If either the salt or sugar is added to the bubble solution, then the standard solution’s ability to create big strong bubbles will be affected.
Material:
· Soap solution in flask · 3 small plastic cups · Sugar container (Red) · Salt container (Blue) · Spoon · 4 small straws ·
Note: Rinse and clean both the straws and the spoon after each use to avoid cross contamination of the solutions!
Procedure:
1. Label the three drinking cups as 1, 2, and 3. Fill each of the three cups to an amount of approximately ½ of its total volume with bubble solution.
(If any of the solution spills on the lab bench or floor wipe immediately with a paper towel to prevent slippage or falling).
2. Add a teaspoon of salt to the second cup, as well as a teaspoon of sugar to the third cup. Stir the solutions within the second and third cups for one minute (with different stirrers) until the solid material that was added has dissolved.
3. Dip the drinking straw into cup 1, remove it and blow gently into the straw to start making bubbles. See if you can determine how well you can blow bubbles. Continue to practice making large bubbles until you feel you have reasonable control over the size of your bubble.
Repeat the procedures written above with the mixtures in cups 2 and 3, rinsing the straw after each use.
