Soda Fountain

In this science fair, I will be crafting a Soda Fountain from basic tools you can possibly find around the house. And my goal is to find out how far water/ beverages can move vertically.

Question: How far can the water go vertically and how long does it take?

Hypothesis: It will go up to at least 5 feet before stopping.

Procedure: I will run several tests, Once a test is done, I will escalate the cup by 1 foot and will re run the test until it won't reach the cup.

I have created a simple and non costly project, the soda fountain. I will not take credit for making this device, for it was produced by MAKE Magazine. I tested the distance that the fountain would go vertically. The farther the tube is, the shorter it’s going to climb vertically from the limited air pressure. I measured the distances with 3 test per measuring. The Soda fountain is an air pressure based project where how far you go, it won’t affect the distance, but how high it can go. And I will test the limits of the Air Pressure and will see how far the average requirement is to properly use it.

For the first measurement, I put the tube up vertically to a cup on the top of my fridge, at five in height. then I put the machine down to the ground only 5 feet away. As I clicked the button, I see as the water extracted from the bottle went to see how far it can go. It almost reached the top where it was at 140 cm. Test #2 Fell by Test #1 by 141 cm. And Test #3 was 140 centimeters, just as Test #1 was. The average of this measurement was 140.4 cm.

For the second measurement, I kept the cup in place on top of the fridge and put the Soda fountain farther by 5 feet, making the tube a bit steeper than before. I ran the machine to test my results by three tests. Test #1 fell a fair distance away from the first measurement, by it being 114 cm. Test #2 went OVER Test #1 being 116 cm. And Test #3 went in between the two tests as 115 cm. For the Average, I have 115.9 cm.

For the final measurement, I kept the cup in place on the fridge, and fell back another 5 feet, making the end distance 15 feet. I ran the tests and see that it falls WAY too short compared to the First measurement. Test #1 was 82 cm, 60 centimeters shorter than the beginning. Test #2 landed about 86 cm. A bit farther than the last test. And Test #3 landed at 89 cm, Increasing with each test. The Average of this measurement was 85.2 cm.

With all the data combined, I have concluded that the proper length for the machine to be used efficiently at 96.2 cm. It will be perfect height and no worries about the water/ soda failing to reach it’s destination.
