Moment of Inertia Spinner

thingiverse

In our school, the equipment we use for rotational motion labs is over $200 for a single lab setup. The Moment of Inertia Spinner is designed to replace the expensive equipment with something that is much cheaper and easier for students to set up. The entire lab setup for two students is less than $1, and the spinners are robust enough that they shouldn't break even if they are dropped.
