Research question: How long can the stream of water maintain it’s ‘bend’ before returning to its original position?

Hypothesis: The stream of water should be able to maintain the ‘bend’ in the stream of water for about three minutes.

Variables: 

Independent: Degree of 'bend' of water

Dependent: Time taken for water to return to its original position

Constant: Size of the stream of water, size of the balloon, amount of charges, material of the balloon, amount of air pumped into the balloon, speed of metronome, number of times balloon is rubbed against hair, distance between stream of water and balloon 

Procedure:

1. Make a scale and place it behind the water faucet (Ensure that the stream of water is flowing straight along the line drawn on the scale)

2. Place a small distance scale on top of the tap to roughly estimate the distance 

3.  Use the balloon pump to pump up the balloon (about 10 pumps)

4.  On the water faucet

5. Rub the balloon against hair (about 50 times)

6. Use a metronome to ensure constant speed when rubbing (150 BPM) 

7. Place the balloon near the faucet (about 1cm)

8. Take a video of the process

9. Do not move the balloon until the stream of water has completely returned to its original position. 

10. Repeat the experiment again for another two times

11. Use the online protractor tool to measure the degree of the 'bend' in the stream of water

12. Tabulate the results for easy reference

Results:

Time taken for stream of water to return to original position
1st attempt	2nd attempt	3rd attempt	average
3 min 26s	3 min 40s	3 min 12s	3 min 26s

Table 3 shows the time taken for the stream of water to return to original position

Data Analysis:
Mini experiment 2:

Original hypothesis: The stream of water should be able to maintain the ‘bend’ in the stream of water for about three minutes

From the background research conducted, not much information is found on the time taken for static electricity to disperse. It is known that static electricity disperses fast, but there is no exact timing given. Another mini experiment is conducted in order to find an estimated timing of how long static electricity takes to disperse.

The results as seen in Table 3 in appendix A shows that static electricity disperses at an average timing of 3min 26s. By rounding down the timing to the nearest minute, it would take about 3mins for the static electricity to disperse, proving the hypothesis correct.

Conclusion:
The stream of water is able to maintain the ‘bend’ in the stream of water for about three minutes.
