Summary
In this quick Design Squad build, kids try a balancing trick and discover where an object's balance point hides. It's a hands-on engineering challenge — plan it, build it, test it, and make it better — that shows where the center of mass is and why it matters for balance.

Discussion questions
Talk it over after the build:
- What problem or goal was this build trying to solve?
- What materials and shapes made it work — where the center of mass is and why it matters for balance?
- If you built it again, what one change would make it work even better, and why?
