20 pcs Tornado in a Bottle Set

Tornado in a Bottle Kit – Turn Two Bottles into a Whirling Science Lesson!
Bring the power of nature indoors with our Tornado in a Bottle Kit—a hands-on STEM experiment that transforms ordinary plastic bottles into a mesmerizing vortex simulator. Perfect for classrooms, science fairs, or curious minds at home, this kit makes fluid dynamics, density, and atmospheric science visible, tangible, and unforgettable.

🔧 Product Features
(1) 20 vibrant PP plastic connectors (mixed 4 colors) – durable, reusable, and easy to clean
(2) Dimensions: 3.2 cm diameter × 4.7 cm length – engineered for smooth water flow and secure fit
(3) Universal compatibility: Works with standard 28mm PET bottles (e.g., 500ml–1L soda or water bottles)
(4) Simple setup: Just fill one bottle 2/3 with water, screw on the connector, attach a second empty bottle, flip, and swirl!
(5) No batteries, no mess – powered purely by physics and a gentle twist
💡 Note: Bottles not included. Please remove the inner sealing ring from bottle caps before assembly.

📚 Educational Applications
This deceptively simple experiment unlocks deep scientific concepts through direct observation:

(1) Vortex formation: Watch as water spirals into a funnel-shaped tornado, mimicking real cyclones and hurricanes
(2) Density & displacement: Understand why water (denser) sinks while air (lighter) rises—and why two substances can’t occupy the same space simultaneously
(3) Atmospheric science: Relate the model to real-world weather phenomena like tornadoes, typhoons, and storm “eyes”
(4) Scientific inquiry: Test variables—water volume, swirling speed, bottle size—and analyze their impact on vortex strength and duration.

✅ Safety & Quality Assurance
(1) Made from BPA-free polypropylene (PP)
(2) Smooth edges, no small parts—safe for children ages 6+ with basic supervision
(3) Non-toxic, odorless, and dishwasher-safe for repeated classroom use.
