CrunchLabs by Mark Rober The Crunchinator
A hand-cranked crusher that shows how gears multiply force
For teens and young adults, the best gifts are the same tools engineers use: microcontrollers, single-board computers, soldering kits and advanced builds. Each pick leads to real projects, portfolio pieces and skills that carry into school and careers.
