Tops TRIZ Cases
- Fluid-Chamber Spinning Top for Stable Long-Duration Spin
Dissimilar liquids separate into visible bands during rotation, boosting inertia to stabilize spin and reduce the force needed to start the top.
- Rotatable Play Ring With Fixable Flywheel for Image Selection
A movable end-cap and flywheel structure lets the toy spin freely, then stop and lock for image selection on a printable surface.
