Abstract Purpose The purpose of this science fair experiment was to learn what things affect the scatter of paintballs and how to build the best paintball marker (gun). We decided that accuracy of paintball guns doesn’t matter because paintball players don’t aim their markers (with crosshair, scope, etc.). They shoot one or more rounds as tracers to the target and adjust their aim. Hypothesis My hypothesis was “By understanding things that affect paintball gun scatter, I can pick the best set up for a gun and show it is the most accurate.” Procedure This is a short procedure. We have a longer procedure listed in my report.

1. Get three paintball markers, four barrels, and six paintball types. 2. Hold 18 trials of 20 paintball shots each. 3. Record data after each shot. 4. Figure out which marker, barrel, and paintball were best.

Results I recorded the location that each paintball hit on my target for each of the trials. I had my father help me figure out the math for two kinds of errors on each trial. Conclusions I concluded that I proved my hypothesis. I was able to learn enough about barrel length, the markers, and paintballs to pick the best setup for playing paintball. I learned that it doesn’t matter if your paintball marker is cheap or expensive, because the results and graphs showed that they are almost the same. I learned that the 12-inch barrel worked the best because it is not too long and it is not too short. The 14-inch barrel was worse than the 12-inch barrel for the two expensive markers. The 14-inch barrel worked a little better than the 12-inch barrel for the cheaper gun G3. I learned that paintball P5, is the best paintball because it has a thicker shell to go through brush. It also cost more than the other paintballs. I know this because I have looked at about four different charts that say the same thing.


Purpose The purpose of this science fair experiment was to learn what things affect the scatter of paintballs and how to build the best paintball marker (gun). We decided that accuracy of paintball guns doesn’t matter because paintball players don’t aim their markers (with crosshair, scope, etc.). They shoot one or more rounds as tracers to the target and adjust their aim.

Hypothesis My first hypothesis was “By understanding things that affect paintball gun scatter, I can pick the best set up for a gun and show it is the most accurate.” After doing research I found out that scatter matters more for playing paintball, so I had to use scatter. Accuracy means that the ball hits where you aim, but in paintball there is no way to target your marker on a spot. Scatter is more important because you adjust your aim after you see where your last shot hit. Bigger scatter makes it harder to adjust your aim and hit your target.

Procedure I had procedures before, during, and after my experiment. I didn’t think I had this many procedures when I started this science fair project. I found out we had not planned out the project and I learned more about the experiment procedures we talked to more people about paintball. My first set of procedures before I started was:

1. Don’t consider human skill in the experiment. Use a fixed tripod. Develop tripod. 2. Decide which things can affect targeting accuracy of a paintball gun. 3. Pick two to four of these things as my independent variables. Examples are gun quality,

paintball quality, and barrel length. 4. Write a list of safety rules for using the paintball gun. Follow rules. 5. Have adult present during experiment. 6. Think about things that could add error to my experiment and try to avoid them. 7. Think about experiment controls that might help find error. 8. Run numerous trials for each independent variable. 9. Measure accuracy of paintball targeting in each trial. Measure the scatter of the

paintballs on a target. 10. Record data from each trial. 11. From looking at the data, decide which set up should be the most accurate.


12. Assemble most accurate set up. 13. Run numerous trials for the most accurate setup. Record data. 14. Compare data to other trials. See if hypothesis is correct.

After I learned more I had three procedures. They were before, during, and after the experiment. Procedures before the experiment: 1. Research topic, visit paintball stores to learn about markers, paintballs. Decide which things

affect paintball scatter. 2. Pick a few of these for my controls (marker, barrel, paintball).

a. What is the best paintball? b. What is the best marker? c. What is the best barrel length to use for markers?

3. Make my equipment (apparatus) a. Tripod to hold gun. b. Target with grid to measure location of paintball hits.

4. Obtain equipment a. Rio Rancho Paintball Emporium let me borrow two markers and three barrels, CO2

canister. b. I used my own marker and barrel. c. We bought different types of paintballs, expensive and cheaper.

5. Plan for safety during my experiment a. Wear safety equipment. b. Follow gun safety rules and safety rules for markers c. Have an adult present.

6. Think about fixed controls during my experiment to reduce experimental error. a. Aim, human skill – used tripod b. Distance – fixed for all trials (84 feet, 6 inches) c. Temperature – same during whole experiment (53ºF) d. Wind – very light wind for all trials

7. Decide how I am going to measure scatter error in the experiment. My father and I talked about different ways. I picked two:

a. Maximum Radius – This is the radius of a circle from the center of the scatter to the furthest shot

b. Average Radius – Add up all of the radii from each shot to the center of the scatter and divide by the number of shots.

Procedures during the experiment: 1. Pick up borrowed equipment from Rio Rancho Paintball Emporium. 2. Follow safety rules 3. Record temperature. 4. Record trial equipment list for each trial. 5. For each trial use 20 paintballs. Record paintball hit location after each shot. 6. Wash off target after each trial with hose.


7. Repeat process for all 18 trials. This took me 5 ½ hours with my father’s help. 8. Clean up. 9. Return borrowed equipment. Procedures after the experiment: 1. My father set up an Excel spreadsheet that would do the math for finding the scatter errors.

The math did these things for each trial: a. Find the center of the scatter b. Pick the Maximum Error c. Figure out the Average Error

2. I entered data from each trial into the Excel spreadsheet 3. My father showed me how to make tables, bar charts and graphs with Excel

a. Draw the scatter graphs for each trial b. Make bar charts of all the errors for each trial. c. Print the table of all trial results

4. I shot paintballs at the target to dry for my experiment display. 5. I looked at the table and bar charts and decided which things affected paintball scatter and

which things were best. 6. I wrote the conclusions and report. Equipment for my experiment was three markers (guns), four barrels, six types of paintballs, CO2 canister, safety equipment, target, measuring tape, water hose, and a thermometer. I gave my equipment short names that were experiment controls (marker, barrels, and paintballs). My control equipment is listed below. Markers

G1 – Spyder Vector 2 G2 – Spyder Shutter (set hot – paintball comes out faster, velocity higher) G3 – Brass Eagle After Burner

Barrels

B1 – 9 inches B2 – 9.5 inches B3 – 12 inches B4 – 14 inches

Paintballs

P1 – GAP black paintball (new) P2 – Wild Streak orange paintball by Brass Eagle P3 – Metallic Gold and purple paintball P4 – Scorch red paintballs by Draxxus P5 – Evil yellow paintballs by Empire P6 – Misk red and white paintballs (1 year old)


Results I didn’t realize that it would take five and a half hours to test all of the things I had planned to learn more about paintball scatter. I wrote down all of my experiment data in my notebook during the experiment. For all the experiment trials the distance from the paintball marker to the target was 74 feet six inches. The temperature was 53 degrees Fahrenheit. The fastest experiment was testing six paintballs with the same barrel and marker. These charts show where the paintballs hit for each trial.

Trial of Six Different Paintballs

Independent variable = paintball, Control = marker #1, barrel #3, Scale = inches 20 paintballs per trial

The next set of trials took the longest to measure. It had three different markers and four different barrels. I wanted to test all of these because I wanted to know if a certain gun did better with a different barrel. These charts show where the paintballs hit for each trial.

Conclusion I concluded that I proved my hypothesis. I was able to learn enough about barrel length, the markers, and paintballs to pick the best setup for playing paintball. I learned that it doesn’t matter if your paintball marker is cheap or expensive, because the results and graphs showed that they are almost the same. I also learned that the speed of the paintball coming out of the marker doesn’t matter that much. Marker G2 was set “hot,” which means the paintball comes out faster than the other markers. The paintball store set G2 to be 300 feet per second or over. The other markers were about 250-275 feet per second. I think it is still good to get an expensive gun because it would probably be better so the marker won’t jam as much. I learned that the 12-inch barrel worked the best because it is not too long and it is not too short. The 14-inch barrel was worse than the 12-inch barrel for the two expensive markers. The 14-inch barrel worked a little better than the 12-inch barrel for the cheaper marker, G3. I learned that paintball P5 is the best paintball. It has a thicker shell to go through brush. It also cost more than the other paintballs. Paintball P5 had about twice as accurate scatter as the other paintballs. Well this project was really cool, and I had fun with it. I would like to thank Rio Rancho Paintball Emporium for letting me borrow paintball guns and barrels. If you ever want to paintball you should get al of your supplies from Rio Rancho Paintball Emporium. You can get the best equipment from my science project there. They are the 12 inch barrel, the evil paintballs by Empire, and the Spyder Vector 2.

Bibliography I could not find any books on paintball accuracy or scatter, so most of my research was done looking on the Internet and talking to owners of stores.
