Crank the Biggest Gadget of All: Your Brain!

Explore motion, mechanics, and more

Put gravity, compression, tension, and torque to work as you build a model bridge to cross a canyon, then test your creation to see if it can stand the pressure. At the Pulley Chair, use simple machines to overcome gravity and lift yourself off the ground.
