Gravity and Zero Gravity

I am so glad that this blogspot is going better than I first imagined.
I hope this blog hopefully affects and answers the curiosities of other fellow student scientists.
To celebrate this occasion, for the first experiment, I decided to test about the thing that always affect us: Gravity.

Tools: Empty bottle, Needle, Water.

Introduction:
What is the difference between gravity and zero gravity.
The difference can be found from whether we can feel it or not.
Frankly, there is no such thing as zero gravity because gravity is everywhere.
The term zero gravity got its name because it is nearly impossible for us to feel or even see the existence of zero gravity.
Using three simple tools above, we can see the existence of no gravity.

Procedures:
1. Put a hole on an empty bottle.

2. Fill the bottle with water.


3. Check the water flow from the hole.

4. Drop the water bottle and observe the stoppage of water flow.

Observation:
The water flowed while holding. However, the flow stopped when the water expirienced a free fall.

Discussion:
The reason why water flowed from the bottle is because force uplifting the water from the bottom of the bottle and the gravity squeezed the water to flow out of the hole.
The water stopped flowing from the bottle because the force uplifting the water turned downward by the free fall.
Therefore, the water instantly experienced the state of being in zero gravity.
