On this the fourth Thursday of April, Megan attended her third Take Our Daughters and Sons To Work Day at NIST.  She was in Dad's group # 24.  She participated in Bill Phillip's demo with liquid nitrogen and laser cooling, the Toastmaster's speech class,measuring tape measures, robot sensing, optics and light, and body armor.  A little break from school and lunch with dad at work are always a refreshing change of pace.
