A pulley is a wheel that changes the way you pull a rope.
The blue arrow is the crate's heavy weight pulling down. The orange arrow is how hard you pull. More pulleys make your arrow shorter!
With more pulleys sharing the load, you pull with less force — but you must pull more rope. The meters show your pull in kg and how much rope you've pulled.
2 pulleys = half the pull. 3 pulleys = a third of the pull. Lift it all the way for a confetti cheer!
