   1. Did you know? The biggest hydraulic digger in the world has a bucket that can hold up to about 85 cubic yards (65 m3) of stuff at a time. That’s like 400 bathtubs’ worth!
   2. When you bake at home, you use cookie cutters to shape one batch of dough at a time. But big bakeries have to make many, many batches! Hydraulic cutters help them shape lots of dough at once into bread, scones, and other tasty treats.
   3. To help them study coral reefs and other ocean environments, scientists have invented a robot jellyfish that gets around with hydraulics. The robo-jelly has two tiny hydraulic pumps inside that let it swim and steer around with ease.
