Your boost helps me create more models like this – thank you!
This is a classic physics demonstration: a double cone that appears to roll upward on diverging rails.
Although it looks like it is moving against gravity, the center of mass is actually moving downward, making this a fascinating and counter-intuitive experiment.
It’s a great educational model for explaining center of mass, gravity, and geometry.
