Cool Girls will be building a Rube Goldberg machine and entering the Boulder Library contest. We are so excited to see what the girls create. They have great imagination and unique ideas. If you want to help our girls to design a killer creation, email us at CoolGirls.ScienceArt@gmail.com.

If you want to see their creation, stop by the Boulder JCC on Dec 10 from 1 – 5pm.
