Construction of the Momentum Machine

                                                                                   Materials needed
                                                                                  •    A rotating chair
•    2 5lbs. weights

The momentum machine doesn't require any construction.


Directions

    Sit in the chair with a weight in each hand.  Then stretch your arms out.  Have a partner rotate you slowly.  Once you’re spinning, have that person let go and move out of the way.  If you pull the weights toward your body, you will notice that you will rotate faster, but be careful because if you spin too fast then your chair might tip over and you might get a little dizzy.
