## Overview

This pack of 10 Rattleback Physics Curiosities offers a unique way to explore Newton's laws of motion. Each semi-elliptical rattleback measures 3-7/8" long and comes in assorted colors, making them perfect for engaging educational activities. The included lesson plan provides structured guidance for teachers and parents alike, ensuring a fun and informative experience.

## Description

Rattlebacks are plastic semi-elliptical shapes, 3-7/8" long, that illustrate Newton's laws of motion, while mystifying kids. Set them down (the rattlebacks, not the kids) and their offset center of gravity makes them spin. Spin them in one direction and they stop and reverse themselves. You get a package of (10) in assorted colors or single solid color, along with a lesson plan and suggested activities.

    The more you know the stranger it seems
  

*by K***N on Reviewed in the United States on December 24, 2018*

Brilliant toy to stump your know-it-all friend.  If the laws of physics are reversible, why does this object only spin in one direction and not the other?  It has no internal parts, but it will only spin in one direction.  How can that be?  Quite a puzzle!
