10K views · 115 reactions | Creating a vortex or whirlpool helps flood water drain quickly by reducing pressure at the center and increasing flow at the edges. This demonstrates the principle of angular momentum—water flows faster when it moves in a spiral! ️ #WaterFlow #VortexEffect #WhirlpoolDrain #FloodControl #NaturalPhysics #FluidDynamics #QuickDrain #WaterScience #EfficientDrainage #DrainSolutions | Michelle Reyes | Facebook

🌪️💦Here's a fab science experiment!We used a bottle to create a whirlpool vortex, we carefully poked a hole in thebottom of our bottle to allow the water to suck through and make our vortex last longer, we also added a drop of washing up liquid to make it more visible.A vortex is created when a rotating liquid falls through an opening. Gravity is the force that pulls the liquid into the hole, and the rotation causes a continuous vortex to develop swirling the water in a bottle. 🌪️💦 #kidsacti
