Take a brick shaped object such as an empty matchbox or a box of tissues.
Spin the box freely in the air about each of its three axes, x,y and z.
You can do this by holding opposite faces at the corners and imparting a twisting motion as you throw it up.
You will find that the box spins sedately about two of the three axes. However it wobbles and oscillates as it turns about the third.
