Spinning Toys

I have grouped spinning toys together because they all share similar factors.

• A center of rotation (fulcrum)
  
• Distribution of weight effects the rotational momentum
  
• rotational force (torque)
• leverage
• Balance (center of gravity)
• air resistance

These factors all affect the design of a spinning toy and are an interesting avenue of investigation.

A project that I do with a whole class.  It is well worth the effort to gather the materials. You can learn the basic tricks quickly and more difficult tricks are shown on the internet at sites like Luna Sticks. Juggling sticks are a great antedote to screentime!
