Bubbles??? Yes bubbles:)

Alright...So here's the problem. Would Salt or Sugar make a better bubble? Yeah I know, I know! You can't blow a bubble with just salt! But if you combine it with water and soap, you are in for a pretty fun experimient! So take a wack at this fun easy experiment and see for yourself if Salt or Sugar make better bubbles.

Materials:

• 3 plastic cups
• liquid dish soap
• measuring cup and spoons
• water
• table salt
• table sugar
• drinking straw

Procedures:

1. Label the cups; 1, 2, and 3.  Measure and add one teaspoon of liquid dish soap to each cup.  Use the measuring cup to add 2/3's cup of water to each cup.  Then swirl the cups to form a clear mixture.  CAUTION: wipe up any spills immediately so that no one will slip and fall.
2. Add a 1/2 teaspoon of table sugar to cup 2 and a 1/2 teaspoon of table salt to cup 3.  Swirl each for one minute.
3. Dip the straw into cup 1, remove it, and blow gently into the straw to make the largest bubble you can. Practice making bubbles until you feel you have reasonable control over your bubble production.
4. Repeat step 3 with the mixtures in cups 2 and 3.

Observation:

Cup 1; has green dish-detergent in it and water. Because of the green dish soap the water has a slight green color to it.

Cup 2; has green dish-detergent, water, and sugar in it. Like Cup 1, Cup 2 also has a slight green color to it because of the green dish soap. But it also has a slight milky color to it, when compared to Cup 1.

Cup 3; has green dish-detergent, water, and salt in it. Like Cup 1 and Cup 2, Cup 3 also has a green color to it because of the green dish soap. But when compared to Cup 1, Cup 3 is very very milky.

Hypothesis:

Starting with Cup 3. I'm guessing that Cup 3 will have a greater struggle making the bubbles. Only because the solution looks "heavy" compared to Cup 2 and Cup 1's solutions.

Next with Cup 2. Cup 2 do will do better than Cup 3 with making the bubbles. But still will have a slight sturggle seeing as there is sugar added to the solution.

Last Cup 1.  Cup 1 will do the best out of all of them. Since there is only dish soap in with water.

Experiment:

Cup 1: Bubbles are easy and smooth to produce. Bubbles don't require a gentle blow to make them. They can also be produced with a forced puff of air. Bubbles bounce and stick to surface for more than 10 seconds. Easy to make nice good sized bubbles. The color of the bubble is a good "rainbow".

Cup 2:  Bubbles are easy and smooth to produce. Bubbles don't require a gentle blow to make them. They can also be produced with a forced puff of air. Bubbles bounce and stick to surface for more than 10 seconds. A bit of a challenge to make nice good sized bubbles. The color of the bubble is a good "rainbow".

Cup 3: Bubbles are harder to produce. To make bubble you must blow gently and carefully. Bubbles pop easaly compared to Cup 1 and Cup 2. Color of bubble is more clear. Hard to make a good nice sized bubble.

Conclusion: 
While observing the bubbles produced by the solutions: cup 2 had the same ability to make bubbles as cup 1 but the bubbles in cup 1 were larger.  The solutions in cup's 1 and 3 had differences in their abilities to produce bubbles.  Cup 1 gave the bubbles a "rainbow" look while cup 3's bubbles were clear.  Cup 3 would produce bubbles but not any at a good size while cup 1 produced good sized bubbles.
The solutions with the table salt and sugar produced bubbles but they weren't as big as the solutions without.  Therefore it affects the ability for the solution to hold together while its being expanded by air.  Creating our own experiment we would change the salt to pepper and see the effects of pepper on the solution.  The hypothesis we created is that it will not have much effect on the solutions ability to create bubbles.
