Air Pressure Fountain Kit – DIY Science kit

DIY Bottle Fountain Science Kit – Explore Air Pressure, Gravity & Vacuum Through Hands-On STEM Learning
Ignite curiosity and deepen scientific understanding with our DIY Bottle Fountain Science Kit—a simple yet powerful experiment that brings core physics concepts to life using everyday materials. Perfect for classrooms, homeschooling, or curious young scientists at home!

🔬 How It Works: Science Made Visible
This kit demonstrates the fascinating interplay between gravity, air pressure, compression, and partial vacuum in a closed system:

(1) When an upper water-filled bottle is inverted, gravity pulls water down through the connector tube. This compresses the air in the lower bottle.
(2) As water drains, a partial vacuum forms in the upper bottle, causing pressurized air from below to rush upward through the fountain tube—launching a dramatic jet of water!
(3) The cycle repeats each time the bottles are flipped, offering repeatable, observable cause-and-effect learning.

🧪 What’s Included
1 × Precision-engineered PP plastic bottle connector 
2 × Durable plastic straws (for fountain and drainage tubes)
🌊 Note: Bottles not included. Kit fits standard 28mm PET bottles (e.g., soda/water bottles). Remove the inner seal ring from caps before assembly.

📚 Educational Applications
Ideal for STEM/STEAM curricula, this kit helps students explore:

(1) States of matter: Why gases are compressible but liquids are not
(2) Gas laws & pressure dynamics: How changes in volume affect air pressure
(3) Scientific method: Form hypotheses, test variables (bottle size, water level, tube length), and observe outcomes
(4) Critical thinking: Troubleshoot why the fountain works—or doesn’t!
(5) Great for elementary to middle school science fairs, after-school programs, or interactive demos in physics and earth science classes.

✅ Safety & Quality Assurance
(1) Made from non-toxic, BPA-free polypropylene (PP)
(2) Smooth edges, no small detachable parts—safe for ages 6+ with adult supervision
(3) Reusable and easy to clean
