2. Hypothesis and Theory
 Hypothesis
Surface tension is the force which makes fluid surface acquired the least area possible. Its direction
is parallel with fluid surface and perpendicular with the edge of surface is act by force in anydirection. In molecules at the surface is act by force in only under direction. So, that made fluid
have surface force act into center. We can see it normally in daily life when we drain water into
tube. Then, water surface is concave down because water in tube have surface tension with surface
adhesion force and cohesion force. It’s call capillary action. And gravity is also one of variable
that can affect to capitally action. So, I think that if we drain water into a small tube such as plastic
syringe and then observe it in zero gravity condition how difference of surface by compare with asyringe in normal gravity condition.

 Schematic Model Mathematical and Theoretical Hypothesis (If applicable)
The height of liquid column is given by
h = 2γcosθ/rρg
we can apply this equation to find θAsian Try Zero-G 2023 Proposal Form （Attachment-3）

γ is the liquid-air surface tension (energy/area)θ is the contact angle
ρ is the density of liquid (mass/volume)g is acceleration due to gravity (length/time^2)
r is radius of tube (length)

3. Verification Methods and Procedures Overview of the Verification Methods
Compare and analysis syringe in zero gravity condition and compare contact angle(θ) fromequation with contact angle from experiment.
