Brownies Science Night

The Brownies went to their annual Science Night at the University 27 Feb...as usual it was a blast!  They had fun with the enthusiastic Instructors who delivered hands on experiments and demonstrations. A portion of this Science Night was tailored to meet the requirements of the SSSS Badge {Sound,Surround, Soothe, Stimulate}.  I took a lot of pics that night but I try not to post too many with the girls face directly.  Also, cropping makes the pics a bit blurry...but here is what I could salvage from the event!  Enjoy!
