Double Cone Uphill Toy – Gravity with Science!

🎢 Double Cone & Roller Uphill Toy – Defying Gravity with Science! Watch objects roll UPHILL and defy common sense! This educational toy demonstrates fascinating physics principles through two seemingly impossible behaviors: a double cone that rolls uphill, and a cylinder that can be "programmed" to climb or resist movement using weights. Perfect for classrooms, science fairs, or curious minds! 🔬 What Makes This Toy Special? Unlike simpler versions, this model includes two extra elements that elevate the learning experience: 1. The Uphill Double Cone Rolls uphill on diverging rails (2° incline) Teaches center of mass and apparent anti-gravity 2. The "Behavioral" Weighted Cylinder Two hidden chambers for 8mm diameter weights Three modes: Climb Mode: Weight positioned high → rolls uphill Resist Mode: Weight positioned low → refuses to roll Neutral Mode: Balanced weights → normal rolling 3. The Neutral Cone Calibrated to stay still on level surface Demonstrates precision physics balance 🎯 Learning Outcomes: ✔ Center of mass & gravity ✔ Inclined plane mechanics ✔ Experimental method – hypothesis testing 🛠️ Setup & Calibration Tips: Requires level surface – use a spirit level Fine-tuning: Lightly sand or add adhesive putty for perfect balance Weights: Use 8mm diameter (80 mm length) rods, nails, bolts! Experiment: Try different weight positions and observe changes 🖨️ Print Settings: Material: PLA (PETG) Layer Height: 0.2mm Infill: 10 - 30% 🚀 Call to Action: 👉 DOWNLOAD and unlock the secrets of apparent anti-gravity! 👉 SHARE YOUR EXPERIMENTS Want customized versions for your classroom? Message me for bulk or modified designs! 👨🔬 Perfect For: Teachers demonstrating physics principles Parents nurturing scientific curiosity Students exploring hands-on learning Makers who love intellectual challenges Because seeing shouldn't always mean believing – sometimes it means understanding! 🧠⚡ Note: The magic isn't in defying physics, but in understanding it better!
