Problem Statement: Which mixture of gases will be forced into the salt water the best?

Method and materials:
Materials
1. 6 2 liter Bottles
2. Reagular air (20% oxygen/80% nitrogen), 40% oxygen/60% nitrogen, and 100% oxygen from Scuba Has
3. 6 liter fresh water
4. 6 tire valves
5. Bike pump
6. Drill
7. Adomotive sealant
8. 5 Jack and the Box salt packets per bottle
Method
1. Drill a hole into the cap of each of the 2 liter bottles
2. Put one tire valve into each of the holes in the caps and circle it with rubber sealant.
3. Take all the empty 2 liter bottles and fill it with one liter of salted water.
4. Take three of the bottles and pressurize each to 80 psi.
a. One is pressurized with regular air (20% oxygen/80% nitrogen) using the bike pump
b. One is pressurized with 40% oxygen/60% nitrogen from Scuba Has
c. One is pressurized with 100% oxygen from Scuba Has
5. Take the other three bottles and pressurize each to 40 psi.
a. One is pressurized with regular air (20% oxygen/80% nitrogen) using the bike pump
b. One is pressurized with 40% oxygen/60% nitrogen from Scuba Has
c. One is pressurized with 100% oxygen from Scuba Has
6. Let them sit over 3 nights
7. That morning open each bottle, take a picture, and rate the amount of bubbles on a scale of 1-3, with 1 being the most and 3 being the least.

Hypothesis: We think that 100% oxygen will rank 1, 80% nitrogen with 20% oxygen will rank 2, and the 60% nitrogen and the 40% oxygen will rank 3.
