Steinhaus longimeter

Okay kiddo, so a Steinhaus Longimeter is a tool that helps measure how long or how big something is. It's like a ruler but it can measure really, really long things like a football field or a big park.

The way it works is pretty cool. The Longimeter has a wheel that rolls along the ground as you move it forward. As you push it along, it counts how many times the wheel rolls. The more the wheel rolls, the longer the distance you traveled.

It's a really helpful tool for people who need to measure long distances like architects, surveyors, or construction workers. They can use the Longimeter to figure out how much space they need to build something or how far apart two things are.

The Longimeter was invented by a man named Hugo Steinhaus who wanted to create a tool that could measure really long distances with accuracy. And that's why we have the Steinhaus Longimeter today!
