The Crimson Five | Book 2

Flip the Silver Switch

By Jackie Yeager

Be Curious. Be Creative. Be Collaborative. Be Colorful. Be Courageous.   

Fresh off their summer at Camp Piedmont, The Crimson Five kids are together again, headed for the Piedmont Global Championships. This time, Kia and her New York teammates travel to Quebec where they’re challenged to solve a new mind-bending task against 99 international teams. But at the Universite de Creativite, they discover a world where inventions like Thought Translation Machines and Clothes Copiers aren’t the only secrets kept. 

The team must focus and unite like never before to solve their hardest task yet if they have any chance of winning a coveted spot on the year-long Swirl and Spark Creativity Tour and keeping their team together. 

Pop the Bronze Balloon continues the award-winning STEM+ series The Crimson Five, building on the inspiring adventures of Spin the Golden Light Bulb.


Praise for the Crimson Five series:

Make[s] space for the audience to solve problems alongside the characters.
