Vortex
Let's break down the principle behind this fascinating experiment in a simpler way:
Principle: The Vortex Dance, when you spin the tube with water inside, you're actually making the water do a special dance called a vortex. This dance happens because of two important forces: centrifugal force and cohesive force.
Centrifugal Force: Imagine you're spinning around really fast. You feel like you're getting pushed away from the center, right? That's the centrifugal force. When you spin the water in the tube, it feels the same way – the water at the center gets pushed outward.
Cohesive Force: Now, think of the water molecules as friends holding hands. They like to stick together because of something called cohesive force. It's like when you and your friends form a circle and hold hands.
What Happens in the Vortex Dance?
Spinning Fast: When you spin the tube, the water inside starts spinning too. But here's the cool part – the water in the center spins faster than the water near the edges.
Centrifugal Force Takes Over: At the center, the spinning is so fast that the centrifugal force becomes really strong. It's like a superhero force pushing the water molecules away from the center.
Vortex Forms: Because the centrifugal force is so strong, it creates a hole in the middle – the vortex. This is where the water can't hold hands anymore because the force pushing outward is stronger than the force holding them together.
Air Sneaks In: The hole in the middle lets air sneak in because there's less water there. This is why you see the water spiraling down – it's like a magical waterfall inside the tube!
Conclusion: So, when you see the vortex in the spinning water, you're actually watching a dance between the forces that want the water to spread out and the forces that want the water to stay together. It's like a watery ballet, and the vortex is the star of the show!

Ale ngin pynsuk ia kane ka bynta ba kongsan halor ka jingtrei kam jong kane ka jingpyni.
Bynta ba kongsan- Ka jingshad jong ka thwei kaba king sawdong ka wan long haba ngi pynshad pyllun ia u tyndong uba don ka um hapoh. Kane jinglong jong ka thwei ka dei na ka daw ba ki don ar tylli ki bor kiba synshar bad ba pynlong. Kita ki dei- Centrifugal force bad ka Cohesive force
Centrifugal force: Mutdur ba phi shad pyllun ha kajuh ka jaka da ka jingstet. Phin sngew kumba don uba ngiat ba phin phet na pdeng. Dei em? Kato ka dei ka centrifugal force. Haba ka um ha tyndong ruh ka shad pyllun, ka ruh ka ialeh ban phet napdeng.
Cohesive force: Mutdur ba ki molecule jong ka um ki bat kti namar ba ki ia long paralok. Ki ia bat lang khlem pyllait bad ia kata ka bor ngi khot ia ka, ka Cohesive Force. Ka long thik kumba phi bad ki paralok jong phi ia ieng pyllun bad bat kti.
Jia kumno hapoh kata ka jingshad thwei kaba king sawdong?
Ka jingthir kaba stet: Haba ia u tyndong phi thir sawdong da ka jingstet, ka um ba don hapoh ruh ka iaid da ka jingthir stet sawdong. Hynrei kaba lyngngoh ka long ba ka um ha pdeng ka kham iaid pyllun kham stet ban ia ka um ba don shajan ka kynroh jong ka tyndong.
Ka Centrifugal Force ka shim kti: Namar ba ka jingshad ka iaid stet kane ka force ruh ka long kaba khlain bha, bad dei hangne ba ka ngiat ia ki molecules ka um sha ka kynroh jong ka tyndong pajih na pdeng.
Ka thwei ba king sawdong ka mih: Namar ba ka khlain palat ka centrifugal force kaba pynlong ia ka, ka mih ka thliew ha pdeng namar ba ki molecules ka um kim lah ban ia bat kti shuh. Ka centrifugal force ka kham khlain ban ia ka cohesion force.
Ka lyer ka rung tuh: Ka thliew hapdeng ka ailad ia ka lyer ba kan rung tuh hapoh namar ba duna ka um. Dei namar kane ka daw kein ba phi ioh i ia ka um kaba iaid da ka jingthir shapoh u tyndong.
Jingpynkut: Namar kata haba phi iohi ia ka thwei um ka dei tang kata ka jingshad hapdeng ki ‘force’ kiba kwah ba ka um kan sa phriang lem bad ki ‘force’ kiba kwah ban bat ia ka um hajuh. Long thik kum ka jingshad hapdeng ki bor bad hangne ka thwei um ka long ka riew kongsan ba mih paw.
