Why do grasshoppers jump so high?

Answer: Powerful spring-loaded legs

Powerful spring-loaded legs ✓ — Correct! Grasshopper legs store energy like a spring. Special proteins in their knees act like rubber bands, releasing stored energy explosively. They can jump 20 times their body length!

They're very lightweight — Wrong. Being light helps, but the key is their leg mechanism. The spring-loaded knee joints provide the explosive power.

Wind helps lift them — Wrong. Grasshoppers jump using muscle power, not wind. Their jumps work even in still air.
