Energizing Brain Breaks Ear and Nose Switch

This is a favorite of my students.

1.  Stand up.
2.  Take your right hand and grab your left ear.  Keep your right arm close to your body.
3.  Now take your left hand and touch your nose.
4.  Uncross your arms and move your left hand to your right ear and your right hand to your nose.  Your left arm should now be closest to your body. 
5.  Switch back and forth as fast as you can.
