The Lazy Lift
How does a lever help you lift something heavy?
Imagine a boulder so heavy you couldn't budge it if you pushed all day. Now imagine lifting it with one lazy hand. No magic. No muscles like a superhero. Just a stick, a log, and a clever trick humans figured out thousands of years ago. That trick is called a lever, and it's about to make you feel a little bit superhuman.
A lever is just three things working together. First, a stiff bar — a plank, a stick, a crowbar. Second, a single point underneath it that the bar pivots on, called the fulcrum. Third, you, pushing down on one end. That's the whole machine. No batteries required.
