Soapy bubbles.

Intro
We are trying to answer the question: does sugar or salt help the relative size of a bubble?
We observed that the light and air flow is constant.
That sugar will help but salt will hinder the bubbles
Materials
1. 3 Plastic.
2. Liquid dish detergent.
3. Measuring cup and spoons.
4. Water.
5. Table sugar.
6. Table salt.
7. Drinking straw.
Procedures
When we came into class we wrote the lab procedure on the board and then proceeded into the lab and began. We first gathered our materials (see above). We then mixed the liquid dish detergent with ordinary tap water to get the control. With our other two cups we added half a teaspoon of table sugar to one and salt to the other. Then using the drinking straw we blew bubbles like little children.

We observed that the sugar added some serious elasticity to the bubble thus making them bigger. The salt make little or no difference to the bubbles.
Discussion/Conclusion
We learned that sugar is a mild adhesive when added with water. We also learned that soap makes bubbles. We could have gone wrong in our measurements of sugar and salt thus resulting in incorrect results.
I accept our hypothesis because our data supports the earlier hypothesis of the lab.
