Experiment 1 - Can we get water to flow with no pressure?

Result: Yes ! It took 35 seconds to fill one litre.

Experiment 2: Does low pressure or high pressure on the straw make the water go any faster?

Result: Applying either low pressure or high pressure makes the water go faster than applying no pressure.

Applying both high pressure and low pressure makes the water go fastest of all !

Experiment 3

Does putting the bottle higher make any difference (with no pressure applied)?

Putting one bottle on the counter: 35 seconds

Experiment 4: Will blue water flow faster than green water?

Green water: took between 35 and 40 seconds

Blue water: took between 35 and 40 seconds
