Chil Balance Sculpture https://www.physicsfunshop.com/search?keywords=chil The mass and orientation of the wings creates a center of mass below this sleek bird's beak- making a system that will rotate and oscillate about a stable equilibrium. No magnets! An elegant sculpture by artist Bin Xu of BinDesign that comes ready to assemble complete with stand. ➡️ Follow the link above for info on where to get this modern balancing bird and other amazing items featured here on Physicsfun | Physicsfun

Switch Pitch Ball http://physicstoys.blogspot.com/p/physics-toy-store.html This spherical assembly changes color by turning inside out when tossed into the air. Advertisements for this toy incorrectly claim air drag is involved in the transformation. The ball is made of multiple components hinged together. In launching the ball from the hand an upward acceleration results in a torque that pivots each component around its center of mass, causing the rotation of these components in an organized wa

Spiral Ball Launcher: spring potential energy converts to kinetic and gravitational potential energy in this fun 3D print. A variation on the spiral “impossible passthrough” fidget toys, the ball exits the stack of rifled guides with stabilizing spin along the vertical direction. The interesting behavior stems from the connection between translational motion and rotational motion and the precision manufacturing allowed by the 3D printing process. Another amazing creation by RJ Design.➡️ Follow t
