Finalised!

After the mini experiment and the small test, armed with new information, I changed my experiment procedure again. Hopefully, this time, the whole procedure can be finalised. 

The water "bending" experiment

“Bending” water using static electricity

Research question: Does the distance between the stream of water and the balloon affect the degree of ”bend” of the water?

Materials: Water faucet, balloon, balloon pump, protractor, ruler, camera, scale, metronome 

Hypothesis: The closer the balloon is to the stream of water, the larger the degree of ‘bend’ of the water. 

Variables:

Dependent: Degree of ‘bend’ of the water

Independent: Distance between the stream of water and the balloon

Constant: Size of the stream of water, size of the balloon, amount of static electricity produced, material of the balloon, amount of air pumped into the balloon, speed of metronome, number of times balloon is rubbed against hair, 

Experiment 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. Rub the balloon against your hair (about 50 times)

5. Use a metronome to ensure constant speed (150 BPM) 

6. On the water faucet

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

8. Take a video of the process
9. Repeat steps 3-8 at distance of 2cm and 3cm
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
